I think thats normal in the crypto industry because it has no guaranteed returns in crypto investments. if anyone has the guts to get involved in crypto investment he/she must be aware that crypto investment is associated with different risks so it's an important matter for everyone who wishes to get involved in crypto, by the way, lessons can be learned along the way if we become more knowledgable in this industry that's why keep, the faith and stay HODL!
Most crypto expert also said the thins that we should learn in crypto investment is not about how we win in every investment or every trade, but we should learn about the money management that we could place in a trade or when we buy coin.
Losing value of investment is usual things happen in every investment instrument and we should be patient and make a great decision in the right time.
