which is good crypto for buy, right now?
None of them. Not just like that.
The first rules are: "don't invest money you don't afford to lose" and "don't ask for investment advises from random people over the internet".
There are a lot of coins around here. Most are scam or bad projects. Some are good or even great projects. Do your own research, carefully, then invest. This way you are the only one to blame and this way you may have less chance for failure. Ah, and diversify. If you invest in 3 coins, or 10 coins, some will fall, some will grow, if you chose right most will give you good results.
Yes, this means a lot of work. But it worth it.

Most fail to inform their audience to educate themselves prior to laying down their cold hard cash.
