In my opinion the best crypto to invest is Bitcoin. Why? Because have a good history, because works as is described on whitepaper, because a lot of people use it, because is a way opener, because is a coin which can be trusted.
right, it's just that bitcoin takes a long time to find a different profit with altcoin. so I think for the best investment is bitcoin and top 5 altcoin marketcap
Even though with bitcoin it could take a longer time to make some decent profits I think this is by far the safest cryptocurrency you could invest in. Also, all the market is following bitcoin, so whenever it is going up the whole market of altcoins goes up, the same thing happens when it goes down.
I think I can choose other coins according to the analysis, but I suggest holding bitcoin, because we know the risk of large market movements, so that your psychology is maintained, especially for beginners
