You've made a really good decision to buy bitcoin at that price, and I myself believe that by the end of the year bitcoin prices could exceed $ 20,000, and I think that bitcoin will break the 50k price
Yes $50k is much easy for bitcoin to reach in this year as in the 2017 the price of bitcoin increased up to 1000 percent so if in this year the price of bitcoin increase up to 5000 percent then we will see the price of bitcoin at $50000. Waiting till the end of the year is a good decision in this year the price will increase higher at some stages it will face a minute decline just like a few days ago but do not worry the price will go upward in long term.
