I want involve this sector fulltime. But is their any ensurity of better future?
Just like how volatile the cryptocurrency market is that will be your chances here in making it big. There is no guarantee that you will make it to the top. So I suggest you start slowly, don't leave everything you have behind just yet. Get yourself used to cryptocurrency before giving it your all so you won't have any regrets in the end.
In this market you need to be prepared for everything. Nobody will give you a guarantee of a clean and prosperous future. The market of crypto-currency is unpredictable and anything can happen. So do not put too much hope.
