The holding costs of these ETFs are roughly between $54,900 and $59,100. Through the cost basis model, we can roughly infer the break-even point of ETF investors, and thus evaluate the impact of profit/loss on investors' psychological pressure. As we can see, since July, the price of BTC has tested the break-even point of ETFs three times at critical moments (7/7, 8/8, 9/6).

Perhaps we can think that if the holding cost of BTC in your hand is the same as or even lower than that of the three major US ETFs, it should be safe in the long run. As long as you hold it patiently, the certainty of making money in the future is very high.
