I am not a great expert, but I have been investing in Bitcoin for more than 2 years.
I am sure that Bitcoin will grow by 200 - 250% next year and many new investors will come to the market
I hope your speculation about the price of bitcoin will come true so we can really sight bull run for this year 2019. I suggest don't stick in investing bitcoin just try to look for another altcoin which you can also gain income. Try to invest in ethereum and in waves which have rapid growing price in this year 2019.
