I like people who are curious, especially about whether there is a possibility of profiting from other alcoins. My answer is that there are always more opportunities in this crypto world, but there are conditions if you say that anywhere you can invest, be the FIRST BUYER, especially if you want to surf Alcoint according to what you want. assuming TA analysis yourself, at least you are on the road and don't enter when the coin/token is flying.
So, about storing your assets, you can use a trusted wallet like Ledger, Trezor, or Trust Wallet. If at your place there is an exchange that has received approval from the local government regarding its operational permit, you can use it for trading, sending and receiving coins/tokens.
