Thanks for a proper answer. That means i have to diversify my coins on a a few wallets for storage if i invest a large amount of money into cryptocurrency. At the moment i have such a low investment, that it is not profitable to swap all my coins into my wallet. Would u suggest to swap only my longterm coins into the wallet? Some exchanges are going crazy now( a friend told me), should i save them all now?
With large amounts I mean 6 digit numbers or more. Maybe 5 digit numbers are a lot of money to you, so doing it at that point might also be sensible. Long term investments should be
kept in cold storage and nothing else. Ignore temporary exchange rates for altcoins, 99.9% of them are useless garbage and in speculative bubble mode.
