I think I lost the crypto I had in my stormgain exchange account (StormGain has migrated its operation to the platform powered by YouHodler)
From now on I think I will only use exchanges that are on the top 50 or 100 by volume... or if you have other suggestions/filters when choosing an exchange?
You intended to keep your coins there by holding for so long and when the time they had migrated or a take over happened, you've missed the notification.
Just go with the top exchanges so that you won't have any problem at all. Not really not gonna have a problem but at least if something goes wrong with them, the news will flood articles on the internet.
Like the last time when ByBit got hacked, you'd see them on headlines and that's one way of notification.
