ALWAYS keep some of everything.
thats the best advice anyone could give you. personally, for every coin i buy i sell one third of it as soon as it triples. that way i get my initial capital back then i can leave the other 2 thirds to moon or drop to zero, whatever happens ill be covered
This is quite a good strategy, generally speaking, sometimes I can force myself to respect that. Other times I just sell 10% after that it has grown 10X, other times the coin gets dumped and I earn nothing or I even lose
But with Oyster I'm holding 100%.
