This technique has worked for me over the years.
That is an excellent strategy, but that means that you have had very good vision regarding altcoins and some good luck, because there are many altcoins that have not yet started since 2018, however I know the logic you apply and it is very good What criteria do you take into account to buy altcoins? do you apply technical analysis? Or do you only buy the altcoins that are closest to the Top of CMC? When the price of Bitcoin falls, what do you do is buy altcoins? What happens is that when Bitcoin falls in price, altcoins tend to fall faster, the important thing is to know at what time you can buy that is the lowest point, since if you buy at some point the same altcoin will fall much more.
