I think bitcoin and many top coins had a nice bull run for the first half of 2019 and have been correcting that bull run since then. This correction should likely end this month similar to 2018 and then next bull run should start.
Timing the next bull market is unnecessary, the system is designed to manipulate the market. In this case, the manipulation of the crypto market will not let the predictions become reality. The small exchanges don't want to send the live, real trading volume to the Coinmarketcap and everything is manipulated. Why do the crypto market traders start to believe in the fair market in every single pump?
The manipulations will end when the cryptocurrency market capitalization increases. Capitalization will increase naturally with the adoption and promotion of cryptocurrencies. Sooner or later this will happen and prices will rise regardless of whether the whales will manipulate the market or not. If not for all cryptocurrencies, then for a large part better days will definitely come.
That's the right path that we should be going, however, it will not happen instantly or easily, we will have to go through a lot of trials before that succeed.
Adoption will come once the market is secured and safe to play with (whether you invest or use it as tool) and with that we need this market to be fully regulated and let's hope that regulators will be positive with crypto so it will not be hard for them to regulate it.
Unfortunately, full adoption in a mainstream will not be possible without the relevant regulations. So, long story short, despite the fact that Bitcoin is associated with decentralization, we are dependent on how quickly governments of individual countries regulate its presence on the financial market.
