If top price of $2.5 is considered bubble, than yes. But, for me increase from 1 to 2 dollars is far from a bubble. Its just a pump.
You shouldn't look at price, the market cap tells a better story.
How is it a buy right this moment? Everything resembles a large correction may occur.
Well the marketcap doesn't exactly tell everything about it either. Only if you have some insider info can you be correct about when to buy, all others, just intelligent guesses.
But IMO you're right, really feels like not to buy atm.
