The lower risk percentage makes Bitcoin a good choice for long-term investment. It cannot be denied that everyone who understands this will of course choose Bitcoin.
However, that doesn't mean that Altcoins are a bad choice, there are times when Altcoins can produce much bigger profits, but again, as I said earlier, everything depends on the risk and what you need to know is that every possible profit will be worth it with all the risks involved faced.
Alternate cryptocurrency is a good investment but it must be in a reportable coins otherwise any shitcoin that doesn't possess the quality of can be easily a waste of investment such as newly listed tokens in the market, that is why many people prefer using their hard earned money to invest into bitcoin to secure their investment. We know that bitcoin is volatile but the volatility of altcoin can't be compared with bitcoin hence is possible of losing its value at any given time and anymore moments.
altcoins that lacks value has crippled many people so I believe that what we need to do is make sure that we watch well and know the life span of a particular we want to invest on so that after the investment it will not be wast of resource, is good to make proper research before you invest in cryptocurrency you wants to invest on, because I know very well that investing in altcoins is like some who is trying a luck, because sometimes they don't be nice as expected before investment.
