Having all your money in Bitcoin isn't wise, anything can happen at anytime and although we aren't praying of the worst things to happen to our Bitcoin but what if your Bitcoin get stolen for some carelessness that you didn't imagine even happening. We can all claim to be very security aware of whatever is going on around us but even top security expertise get hacks at times.
We have other assets that are as useful and valuable like Bitcoin but they're not Bitcoin. You can invest in Real estate and other businesses. All wealthy individuals I know or have read about didn't get their wealth from one source therefore we have to diversify our investments.
Markets finances and trading are my thing.
I been learning all of those many years i don't make decisions easy i calculate and i do have proper risk management.
