Well, it is cool to see an impressive price for the prediction of BTC next ATH. However, honestly I don't believe it will be above $200k in the current cycle. I even have my own prediction that the peak of BTC price will be below $150k.
Even big institutions and governments join BTC investment, I think it won't suddenly raise up to $300k. It should take time to reach a very significant increase in Bitcoin price. At least, it should take 1-2 cycles more to be around $300k.
You are one of the few investors I see making quite modest predictions about bitcoin while there are many who expect and believe bitcoin will hit $500,000 - $1 million in this cycle.
I don't know what people base that prediction on but it seems like people forget that we are talking about trillions of dollars and that is a huge number, not a few million or a few billion dollars. So I agree with you that Bitcoin cannot suddenly reach a market cap of 6 or 10 trillion in such a short time. Even if institutions or governments enter the market, they will plan to invest billions of dollars and this plan will last for many years, not that they will buy massively in a short period of time. So expecting bitcoin to hit $300k, $500k or $1 million in this cycle is unrealistic.
