Bitcoin's spike 20$k on December 2017
What cloud be the next spike level and when???
I expect to see very high prices in 3 years, yes 3 years is far away if we think about it right. But this time the price will increase slowly. For what reason do I believe that the price will increase a lot in 3 years? Many governments will recognize bitcoin, some regulators will approve activities related to cryptos, people will be able to buy cryptos with greater ease. Institutional investors will be able to enter this market because it will be a properly regulated market. The exchange will have to provide good quality services due to the competition and the regulations. all these factors that I mentioned will make the price very high in the next 3 years
Hopefully 2K$.

Bad joke
So we'll see where the next border will be. I also expect it to come in the next few years, up to 2 years. But, nobody knows for sure!
I hope see in 3 years.
