Right mate, I also fear of btc going back to 30k or even less but the statistics about bitcoins' growth potential are singing a different story here. This time won't be a crash but a correction which will give traders a small, yet reasonable opportunity to buy btc somehow cheaper than buying at ath.
Yes, but for now I think it will be a little expensive to buy, moreover the potential for Crash is also still there in an unexpected time by anyone, but for those who dare to risk their risk on Bitcoin will also not be wrong because Bitcoin is a coin worth buying at any time.
Investing in bitcoin is much more risky than investing in other currencies it is possible to invest in this currency all the time but do not be disappointed if the price goes down. The long wait will double the current price it's too late to get down to 30k bitcoin is still likely to rise still a good chance to hold on.
