Today I saw my portfolio go from 5k$ to 4800$ at 9:00PM EST. I was thinking sell all out at 4500$ then buy back in with $2500 if it dips down low as I think this is a year to go long, but there are some things I need to buy in the mean time. So is $4500 a safe number in case it resets back down to 15k$ (Which I will buy back in and HODL)
I think you do not have to sell now because I think the dips will not come too deeper. It's a correction temporary that will always happen. I feel that the bitcoin price will increase back to the higher price so that you can sell it higher than the price you bought, and you can make a nice profit. I do not think that the price will reset and back down to $15k in short time, but the price will make another new ATH soon. But that is a suggestion, and for further info, you can search from the market to see what is the situations of bitcoin price.
