It's true that we have to set aside our money to invest in this bull run because this opportunity only comes once every 4 years, maybe once a generation because the cycle times are very different, so maximize the bull run to get lots of profits in this bull run.
that is if we have enough capital to keep buying because we knew that many of us have already invested our money in this market so having spare will be hard to do , but good for all of us that in 4 years there is an opportunity to profit so invest and should have always spare USDT on hand.
i believe if someone has that plan in mind which is keeping enough USDT to invest, then they are probably already been doing so since when bitcoin was below $40,000 buying around all time high might a bit too risky of an investment for me personally but i also believe that some people are willing to invest right now because they are late and they still see potential with these tokens.
that is why even right now the trading volume is still as massive as ever or even increased, some people are still trying to invest in bitcoin, heck even the big fund investment companies are doing exactly the same thing it seemed that the dream of reaching $100k is not too far fetched in my opinion.
but i do agree that having spare USDT might do good like for example when the price dipping usually the recovery happens within short amount of time and thats good opportunity to buy and make profits.
