This is also a big mistake which many users make, never store all your assets on one crypto exchange. These exchanges are shady and can turn into a scam any day, especially until there is any regulation on them one should keep all their money in one exchange. Keeping them in unpopular wallets is even more risky.
That's right, putting money in one place is very risky, this happened to me because I kept it in my Xapo wallet and after almost 2 years of inactivity I lost my bitcoin and BCH, let alone keeping on one wallet/exchange of course only made us unable to sleep and eat
