The two don't necessarily have to survive one. Bitcoin has been No. 1 from the very beginning, and no one can shake it. The altcoin team will naturally destroy it if they make enough money. They dont want us to do anything. Their purpose is just to make money.
perfect answer and this is why we also wanted to earn from those coins , admit it but almost everyone of us tried to invest or still investing in altcoin for a sole target and that is to earn easily while Holding our Bitcoin for long term plans right?
bitcoin will always be our first choice but we should diversify and that is to put at least some part of our investments in altcoins.
The survival time of many altcoins does not exceed 24 hours. In many cases, you have no time to think and judge. You are already in the abyss, and there is no chance of rescue. This is the biggest risk for many speculators choosing altcoins.
