As indicated by predictions bitcoin should have achieved 15k$ by end of 2017 and fall in first week of jan 2018
In any case, shockingly its effectively reached 17k$ in 2017.
Should I purchase or hold my btc?I don't plan to sell at any point in the near future.
Your question seems unclear. If you are planning to gain maximum profit, you should have bought bitcoin by the month of February. You are very lucky that you have money for buying bitcoin because I don't. Predictions in this forum are quite accurate since the ones producing it are experienced users in this forum and you can trust most of them.
