Hello everyone .I'm new and I lost about 200 usd in just 2 weeks . every coin or token I buy it fall down too quickly . once I bought bitcoin when it was on 94k and I sold when the price rised to 98k but again when the price dropped to 94.700 then I couldn't buy the same amount I sold when it was on 98k . please help and share your expérience . I would love to have your precious ideas . thank you
