However if we could stay above 10500 levels, that also means that we are not willing to drop yet and the pressure could be too high for the seller side. Hopefully it wouldn't be a long term thing and we would go up because I did waited around to sell my bitcoin (bought at $6.5k so no problem) to sell at 2x on $13k but it never reached there, now I am feeling a bit regret that I didn't get out quick enough.
Ultimately, you seem to be both a newbie and overinvested that you are so nervous about price drops and/or that you did not cash out some of your apparently overinvested status.
If you hold for the long term then you can just cash out a bit here and there along the way and not worry about it. One of the problems is to overinvest, which merely causes you to get nervous.
Seems to me that 4 years from now, the price is much likely to be higher rather than lower than our current price, even likely that there will be some decent price appreciation along the way, even though we may have ups and downs along the way, but also seems to be a better place to hold 1% to 10% (or even more) of your investment value rather than in traditional investments... talking longer time horizon.
In other words, if BTC prices go down from here, either holding or buying more seems to be the more prudent approach.
Of course, holding in the event that you are over invested, or buying more in the event that you have not over invested.
Even though it is NOT a good time to sell, if you are nervous, of course you could still shave a bit off of your overinvested amount in order to hedge in the event that BTC prices go down rather than up.
One of the tricks of gaining and maintaining a BTC position is to be both psychologically and financially prepared for price moves in either direction - because sometimes the price direction can end up going against you, at least in the short term.
