Can I buy Ethereum now?

On December 15th, a bunch of analysts called for a crazy bull market. I have been reminding people for several days that altcoins have peaked. In just half a month, many coins have already halved in value. Never enter the market when it is euphoric. There will always be opportunities in the market. Moreover, this round of altcoins has never experienced a real bull market; it has only been rapid increases after shaking out. After a brief rise, it continues to decline to unload. The market will always have opportunities. Never stand on the losing side. Preserving your principal is more important than anything else.
