if I had that kind of money, I wouldn't risk asking people I don't know where to invest it, do a market analysis yourself and make a decision, because the amount is not small. I would pay attention to projects with their own blockchain and the top 10 CMC.
You are completely wrong, as if OP will just listen to the advises here? lol you are fooling people with that.
30 thousand USD and you will just follow what people says?
OP is asking so he will have ideas in which currency to put His money but surely he will make His own research because it is his money and he cannot blame anyone if he fails.
