I've mentioned here before to the point of boredom that I always heard that whoever wants to invest in the traditional stocks and shares market should not put all their investment in one company. The key is to diversify your portfolio. This way, no matter what way the market works you will hopefully earn more than you lose. Isn't the cryptocurrency market exactly the same in this regard?
Yes, it's same as traditional stock and share, never put all the money in one cryptocurrency, it's too risk and don't help us gain more profit than invest in different cryptocurrency, example you put all your money to buy 1 Btc $6500 last week, current price is $4500, then you already lose $2K, maybe you won't lose too much if invest in different cryptocurrency
