Re: Bitcoin price predictions based on actual data / mathematics
I really dont know whats gonna happen but I made my decision to sell btc and buy mostly xrp and some other cryptos and in absence of some convincing mathematics to go back to btc i will stay as is. We will see which one works out better in 10-20 years from now 
I hope you do not sell your bitcoin now because bitcoin will have a chance to break the next higher price.If you do not have an urgent thing that needs money, you should hold your bitcoin and if you have the skills to trade, you can use some of your bitcoin to trade to make more bitcoin.
I can not predict how high bitcoin prices will increase this year because I am sure that no one will know for sure.
I hope all of your coins will increase, so you can have more bitcoin ready to sell in the next ATH of bitcoin.
