In my opinion if you has many bitcoin better you sell, seems currently will continue decline.
What prices are you currently looking at? We have been increasing steadily for a while now other than the crash due to ETF denial.
Even with a mild crash we rebounded back up to $1200+ in less than 12 hours.
I have more faith in BTC now, than I did 1 week ago.
Personally for me, I wouldn't buy Bitcoin at these prices. Bitcoin always has ups and downs in price and I think we are still on the upside. I'm waiting for some kind of temporary drop in price to buy more. There could be some people cashing out gains or whales manipulating the price, but there are always dips along the way.
A year ago when the price bitcoin was about $250, I also wait for the price to drop, I think a year ago the price is very expensive and hope could drop under $100. I continues waiting and after 4 months (halving day) prices skyrocketed to $700, I'm very regret for wasting time and not making a decision to boght. I don't want to repeat the second so that when the price of the bitcoin $600 I bought about 5 btc, don't ever expect the price could drop at this time, better buy it soon.
