That’s the simplest explanation for it, but at any time I would say we must keep the funds in wallets only. The reason for this is current unplanned bans over the exchangers and trading platforms. So if you are up to date with the news around us then you can feel the ban rates have been increased a lot these days. Starting from the china to Korea and even small countries like Indonesia etc got their country people banned from using the crypto currency. How we could really trust the exchangers in such Cold War. Better keep them safe in the wallets and take them out whenever we need to exchange them.
