The answer to this question depends on what your needs are. If you are looking to store only Solana, the pick would be a Phantom wallet, the community loves it. If you are looking to store other cryptos as well and want an easy-to-use and good-looking wallet, Exodus might be the one for you. For those who prefer open-source and want to carry crypto on mobile, the Trust wallet is the one. Defi lovers will love Coin98. If however, you have a large holding, say cryptos worth $1000 or more, and you are a long-term HODLer, you definitely should look into investing in a hardware wallet. It's never recommended to keep all your funds on an exchange, no matter how secure they are. Only keep the amount you are actively trading with.
