Most of 2018 was tough for crypto investors, and most of 2019 hasn't been great either. However, since April, things have started to look a little positive. From April 10, to May 29, Bitcoin has increased by nearly $4,000. That type of growth has been rare for a long time now. For the first time in a while people within my crypto circles have been starting to discuss whether we're about to enter a bull market.
