ETF may bring crisis to Bitcoin, but only the Bitcoin ecosystem can save Bitcoin.
After ETF is approved, more and more Bitcoins will no longer circulate in the institutional vaults, and the online transaction volume will decrease. After the mining cost is halved, the mining cost may rise to over 40,000, and if the price does not rise, the miners will have to turn off their phones.
When the miners turn off their phones, the network security of Bitcoin will be threatened. And the Bitcoin ecosystem is the best solution, which motivates the miners to keep working.
Satoshi Nakamoto said 15 years ago: The transaction volume of Bitcoin is either very large or very small.
The survival of the Bitcoin network is also one of the important meanings of inscription.
