Yes spending time in bitcoin is really worth it. It is life changing actually. When you have enough bitcoin and the right time comes for sure your future is secure. Spending time in bitcoin also makes you updated about technological advancement. Bitcoin can be the future currency.
If you benefited from spending time, you will love what you are doing.
Otherwise if we don't get the benefit, it's just a complete waste of time, personally, I already love bitcoin as it fulfilled some of my dreams.
Investing here is never easy but I believe I'll be successful.
