Do you think about bubble now?
No i don't, i don't even think the word 'bubble' can be associated with BTC right now, it was at the beginning people called BTC a bubble and that the price will fall to zero, all of such people have been disappointed a long time ago, and many of them now buy and use BTC.
Do you think, oppositely, that this correction is nothing like a bubble, and it's only good opportunity for Bitcoin accumulation?
BTC is still above $100k and many people may not see it as a good time to accumulate, especially if they haven't bought any when the price was low. However, for stronger hands, every correction is a chance at further accumulation.
