It is clearly important to hold Cryptocurrency in a Safe Wallet. Please make a list of suggested Wallets, pluses and minuses of each with a link. "Changelly" is at the top of the Stellar Community page and this clearly allows exchange, but is this a safe site? Is it a site to buy Stellar only or store as well?Thanks
There's a list of wallets on Stellar's official site. Changelly is an exchange but you can't hold your lumens there even if you wanted to.
Personally I wouldn't trust any of the wallets, ledger Nano S is the only way to be safe in my opinion.
But yes, Changelly is a safe site. It's well respected.
