As there are many altcoins, multi wallets are very useful and necessary at times, since the altcoins long term stak can make some profits.

And like everything in the crypto world, that is, in the world, wallets are sponsored and spread as the currency sends. This is a short and sincere review of some of the main (and best, simplest and user-friendly, in my opinion) wallets available.

Coinomi

One of the most popular, if not the best known multi available, and a great bet since it in turn supports more than 130 coins, then it will be difficult to run out of places to place your tokens and alts.
Very advanced, it gives you a single seed wich you can control all currencys, in addition to having integrated exchange, very useful in cases of need for quick exchange without having to go to an exchange. My favorite.

Coinbase

Sincerely for me it is not as user friendly and simple as they say to be compared to others, sometimes I even think it tries to hinder your transactions a little since it is also an exchange and you gain something from it, but as it is also a complete exchange it is worth it be cited. It is still backed by some huges and reputable exchanges, one more point. It's also perhaps the most reliable of them. One more.    

Trust Multi Coin Wallet

Very intuitive and easy, it is a good wallet, it only leaks in the absence of a few alts, only supports BTC, LTC, ETH and EC-20 based tokens, which results in just over 40 coins.
The advantage is that it's say it is quite safe and reliable, since it is, among other factors, a non-custodial wallet where you control the private keys.

Cryptonator

Takes control of your keys, so I don't think it's one of the best options as there are so many of them. The advantage is that it supports altcoins not available in others, so I would only use it if I really needed alts in my wallet. What can often be circumvented by the balance on exchanges, but at the same time can be almost essential, depends on your needs. Anyway it is mentioned.

FreeWallet

A little poorly rated in general. I especially hate it due to the (generally) much higher withdrawal and exchange rates it has, and yet another factor: the internal exchange varies a lot and you end up not knowing how much you are actually exchanging and you may end up losing a lot of money, but it can also be especially useful due to the multiple mobile x desktop interface, and zero fees for platform-users trade. Also quoted.

That is, I hope it helped you choose or change your wallet.
