Consider altcoins as gambling, invest the amount you can afford to lose. If there will be price drop, it will be most significant on altcoins, but the bull time will be massive for some altcoins and probably Shiba Inu would be among the altcoins that will have price increase during the next bull run.
But for investment advice, I will advice you to invest in bitcoin.
I used to invest in altcoins because of the fact that they give a chance to earn some money without a huge investment of it. What's your point of view whether bitcoin can give the opportunity to earn because nowadays I see more people who lose money from it instead of earning
Bitcoin is the safest coin in the crypto market, this is the first time I heard someone say that investing in altcoins makes money and investing in bitcoin loses money. It sounds pretty backward.
In the crypto bitcoin is the only coin that will never make you lose if you hold it for a long time, losses only happen when you buy too high and sell when you panic. Panic selling, it's your fault because you have no knowledge, no confidence in what you invest. Don't try to blame others.
