First am not a pro trader, but my trading techniques have proven fundamentals. I recycled around Bitcoin and some handful of good altcoins; I trade with a hand full of funds since altcoins and the bitcoin market move in the opposite direction; I fill my bags with altcoins when the alt markets are down against Bitcoin and sell them when the market is on the rise to buy bitcoin which will be on a downtrend at that moment.
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.
Yes, I agree with you, this is what most traders do and they also make profits from this way.
I believe when it comes to trading you do it the way you understand better.
