Does anybody leave a percentage of their BTC on the exchanges, or do you guys store all your BTC in your wallets, etc?
My current ratio is 100% in cold wallet and 0% in crypto exchange.
Several years ago, when I was a crypto noob, I used to store almost all my BTC in my Localbitcoins account. Luckily, I never got scammed by Localbitcoins(LBC was legit). I also stored small amounts of BTC on other crypto exchanges like HitBTC and Trageogre without getting scammed.
I was ignorant back then. Now, I would never trust a centralized crypto exchange to store my coins in the long term.
Maybe by leaving small amounts of crypto on the exchange you are "flying under the radars" and you won't get scammed. Try leaving big amount of crypto on a centralized exchange and see what happens.
