What kind of coin do you want to keep? In my experience, now most of the coins can be kept in a myetherwallet. But you have to specify the type of coin then I can advise you
That is ERC20 tokens buddy not a coin. Except ethereum and tokens, I do not see the people anyone having other coins on myetherwallet. May I what is the meaning of 'type of coin you have mentioned above'
I see the project only variate from one coin to another coin.
First you learn and understand the crypto currency buddy. Then you come here to suggest the people to invest their money.
