I want to share to you my strategy in managing my coins. 30% of my coins are in the exchange site wallets for faster transaction whenever I want to buy or sell coins. 40% are stored in their own provider wallets and the remaining 30% are on some mobile and desktop wallet like coinomi, jaxx and exodus. This coming January, I'm planning to buy hard wallet which s the Ledger Nano for a tighter security of my coin. Just want to share this, I don't know if it will be effective for you but you can try.
