looking at the unstable market, I hesitate to buy altcoins, which I am afraid of, if I buy now, I can lose, in the opinion of all friends, is it now worth buying altcoins?
Yes, its a good time to buy altcoins. I believe altcoins are very cheap right now. You can earn money not only thru buying and holding, but also from trading. In both bullish and bear markets, there is always money to earn.
