Your friend made a speculative buy and he was lucky that it paid off - nothing is guaranteed in the crypto world. Now could be another good time for buying - or price could drop much further - the tricky part is getting the timing right
Agreed! People have to make their own careful decisions by using their own brains. Never trust anyone who tells you to invest in something or not without thinking on your own. They might be right and they might equally be wrong. Trust your gut and brains and don't invest what you cant afford to lose. at the end of the day there are countless opportunities in every aspect of life, and we can and will always win some and lose some.
