I will take the profits and keep it in stablecoins. I have three options stablecoins, USDT, USDC, and DAI. Splitting into three parts of each stablecoins will be good. I will convert them back to fiat but not all of them because I will adjust the amounts and only do that with what I need. If I keep that in fiat, that will sound the alarm and the bank will investigating my account. They can asks me from where the money and if they are suspicious, they can report that to my government. I don't want that happens so keeping in stablecoins is the good decision for me.
Taking profit in a short period of time is not good for those that want to succeed from BTC hodling to turn to a millionaires, because the last price will not be bigger than the future price and you need to be patient to achieve your right dream from BTC hodling. You can be selling your coins and converter them to stablecoin but you will not going to laugh more than the person that started hodling when the price of BTC was low without selling any of his BTC until the price double up in 5 or 6 years time before he or she can trade to smile with massive profits.
I don't know the country you will come from that will make you to convert plenty of coins to fiat money in your bank account, if you convert plenty of millions in your bank account in my country, the government officials will surely trace your identity to know the type of work you are doing to achieve plenty of millions in your bank account.
