Bitcoin’s remarkable surge past $13,400 on October 29, 2020, wasn’t just being driven by institutional buyers and retail FOMO. The rally, which pushed the world’s largest cryptocurrency to its highest level in nearly three years, was getting a surprising boost from an unexpected corner of the market — Ethereum’s booming decentralized finance ecosystem.
TL;DR
- 0.8% of all Bitcoin in circulation (148,000 BTC) is now tokenized on Ethereum
- Wrapped Bitcoin (WBTC) holdings doubled from 74,000 to 148,000 BTC in just 50 days
- Bitcoin traded at $13,437, up 1.3% on the day according to Kraken data
- Yield farming in DeFi protocols drove massive demand for tokenized BTC
- Concerns raised about Bitcoin blockchain security as value shifts to Ethereum
The Wrapped Bitcoin Phenomenon
The numbers tell a striking story. Ethereum Foundation researcher Justin Drake highlighted on October 28 that 148,000 BTC — representing 0.8% of all Bitcoin in circulation — was now based on Ethereum in the form of synthetic assets like Wrapped Bitcoin (WBTC), tBTC, and others. What makes this figure particularly remarkable is the speed of growth. Just 50 days prior, that number stood at 74,000 BTC. And 23 days before that, only 37,000 BTC. The growth has been exponential, with the total doubling every couple of months.
Wrapped Bitcoin, the dominant player in this space, allows users to lock up their BTC and receive an equivalent ERC-20 token on Ethereum. This tokenized Bitcoin can then be used across the sprawling DeFi ecosystem — as collateral for loans, in liquidity pools, or for yield farming strategies that have become the hottest trend in crypto throughout 2020.
DeFi Yield Farming Drives the Surge
The primary catalyst behind this explosive growth has been the yield farming craze that took over DeFi during the summer and fall of 2020. Protocols began offering eye-popping annual percentage yields to BTC holders willing to deposit their Wrapped Bitcoin into various liquidity pools and lending platforms. For Bitcoin holders accustomed to holding an asset that generates no passive income, the opportunity to earn significant yields was irresistible.
Prominent crypto researcher Hasu captured the dynamic perfectly, noting that “Wrapped bitcoin follows the yield opportunities. The yields we saw for BTC in DeFi have already collapsed a lot, because they were fueled by the retail buyers of tokens like CRV, COMP, UNI, and the countless food tokens. And those buyers are running out.”
Genesis Trading, one of the largest institutional crypto desks, confirmed this trend in their quarterly report, noting that “a major theme in Q2 was the demand for yield on crypto assets” and that they had seen “a massive pickup in interest this quarter in many forms.”
Security Concerns Emerge
Not everyone is celebrating this migration. Nic Carter, co-founder of Coin Metrics and a respected Bitcoin researcher, raised alarms about the long-term implications. In comments reported by Bloomberg, Carter explained that the increasing amount of Bitcoin commerce taking place on Ethereum rather than on Bitcoin’s own blockchain diverts transaction fees away from Bitcoin miners.
This could reduce the economic incentive for miners to keep their machines running, potentially weakening the network’s security over time. While Bitcoin’s mining difficulty adjustments ensure block times remain stable, a sustained decrease in miner revenue could make the network more vulnerable to attacks from well-resourced malicious actors.
Messari founder Ryan Selkis put the scale of the trend in perspective, noting that nearly five percent of all “floating” Bitcoin in circulation is now made up of synthetic assets — a figure that has been climbing rapidly as DeFi continues to attract capital.
The PayPal Factor
The wrapped Bitcoin narrative took on an additional dimension amid rumors that PayPal was in talks to acquire BitGo, the custodian behind Wrapped Bitcoin. While neither company confirmed the reports, industry observers speculated that such an acquisition could bring significant changes to the WBTC ecosystem, potentially opening the door to even broader institutional adoption of tokenized Bitcoin on Ethereum.
Market Context
On October 29, Bitcoin was trading at approximately $13,437 according to CoinMarketCap data, with a market capitalization of roughly $249 billion. The 24-hour trading volume exceeded $56 billion, reflecting intense market activity. Ethereum traded at $386.73 with a market cap of approximately $43.8 billion. Kraken reported total spot trading volume of $274.1 million on the day, slightly above the weekly average of $245.8 million.
The broader crypto market showed mixed signals. While Bitcoin continued its upward trajectory, many DeFi tokens were under pressure — a sign that capital was rotating from DeFi back into Bitcoin as the flagship cryptocurrency’s rally captured the market’s attention.
Why This Matters
The migration of nearly 1% of all Bitcoin onto Ethereum represents a fundamental shift in how the two largest cryptocurrencies interact. For years, Bitcoin and Ethereum were seen as competitors. Now, they are becoming increasingly intertwined. Whether this convergence ultimately strengthens or weakens the crypto ecosystem remains one of the most important questions facing the industry.

doubling every 50 days is not sustainable lol that chart goes exponential then collapses every time
0.8% sounds small until you realize that is 148,000 BTC sitting on a chain that has nothing to do with Bitcoin’s security model
the real question is what happens when those 148K BTC need to come back to the main chain all at once
74K to 148K in 50 days and people still pretended DeFi yield was organic demand
wBTC was always a security risk dressed up as innovation, wrapping BTC on ETH defeats the entire point
