It will be very close to $75,000 then it will arrive in the next few days. 
Make no mistake this is my own prediction.
Reason: It has entered the starting gate for a bullrun, before the ATH halving has occurred then after that the price will be higher, there are many factors why the price of bitcoin continues to rise because the market is getting crowded with the number of investors who continue to enter, believe me this will continue to grow.
Staying a HODLer until $100K or $150K is still realistic.
I checked the price now and it was sitting at $73k. It looks like we are experiencing a consistent growth here, so what you are telling there is possible. We already drop a few times after we hit $70k, so I'm not expecting for any correction at the moment until we reached $75k. To sell now is not what you call a mistake (if this is the mistake you are referring to?), but just ensure that you bought a little earlier, if not, well it may be best to just HODL for a while.Make no mistake this is my own prediction.

I don't see a lot of factors for the growth of the price of BTC aside from the ETF and the upcoming halving. The one that you said where investors continues to enter is only common and always there but I must need to agree that new investors alone more than enough for driving bitcoin prices to test $100k levels in short term. So, continuing to hold would be a better option for right now.
