I own many altcoins - IOTA, NEO, ada, xlm, xmr, trx, gto, xem, sc, fct, ... and I struggle to find a good wallet where to keep them. I don't want to install 1 wallet for each coin that would be crazy. I heard jaxx wallet is not that good so looking for alternatives. Coinoim and other wallets I know of don't support most of these coins. And keeping it at an exchange is not the greatest idea... thanks
You can check Exodus and Myetherwallet. Also, don't forget to have Ledger for the safety reasons.
Exodus is comfortable cause it shows the percentage of your portfolio allocation. But it supports not all the coins.
Myetherwallet is for ethereum token wallet right? it doesn't support any coin like sem, neo and soon. I'll better to suggest to buy a cold wallet like trezor or nano ledger but I don't know also if they support all of the coins/tokens talking by OP.
