From the bull market in 2017 to the present, the price of mainstream cryptocurrency has fallen sharply. How much money do you currently have, you can buy cryptocurrencies in the future market. If the bear market will last for a few years. What do you choose to do?
Bitcoin is the only coin thats worth rushing to buy if it loses big value, for altcoin it can be very tricky because you can't predict if the price will keep falling after you rush to buy on exchange but as for bitcoin there is a bigger chance that it will recover in a short period of time
If you ask many traders how they have been making profit, they will tell you that they buy at dip and they sell at high, and the amount they make depends on the number of times that they get to see dip to buy and sell high, and the only cryptocurrency that would really give them such opportunity is bitcoin, because anytime that bitcoin dips, it is certain that it will surely increase back no matter how little they are, I have never seen bitcoin keeps gown down without having some percentage of high correction later in future.
Most of the altcoins that you see, when you see their dip, you need to first run far away from them, then keep sighting and monitoring them from afar because if you near their dip, you will end up being a bad holder off the coin.
