Holding large amounts of crypto on exchanges brings convenience to trade but inherent risk.
If you are an investor like me, buy on an exchange then withdraw to a person wallet, software or hardware.
There are different types of wallets, some hold many different cryptos, others just one like Yoroi for ADA.
Why would you use Yoroi? You can stake your ADA to earn 5-6% APR per year to earn passive income, alongside the price action.
By moving crypto to a personal wallet you are taking control of it, and you are fully responsible. Just basic good housekeeping and you will be fine.
If you are dabbling with <£1000, then you could argue is it worth taking it off an exchange? Up to you.
