The truth is that nobody actually knows the lowest bottom in cryptocurrency and that is why I said you should use dollar cost averaging. There are people that are using that method to trade in the crypto market and they are making money. If bitcoin eventually goes down to $15,000, then it is profitable you start putting your money little by little. If it goes down again to 12000 dollars you can also invest another portion of your money and from there you may actually buy the bottom but not with all your money.
