What total amount would you invest? How many altcoins would you pick? and what amount per altcoin would you invest? Or go for different amounts for each coin?
I'll give an example to make my question(s) a bit more clear. Let's say I want to invest $250 in altcoins. Would it then be a good idea to pick 10 coins and invest $25 in each? Or is it better to pick 5 coins and invest $50 in each?
I think that you should try to find a good coin or token on coinmarketcap that has strong fundamentals or real life usage, do a lot of research on it and invest a percentage of your available fundings in it-around 40% I'd say. If it is gold it will glitter and when it does you will profit off of the hopefully exponential growth.
