Bitcoin is NOT an investment strategy. Who believe that will get rekt.
Bitcoin is ENERGY stored in the most secured and brilliant way.
What people do every day, every minute? People are always in a continuous run for gathering energy, in many different forms: to eat, to store, to trade, to use it as money, to use it as savings. People depend 100% of energy. People are spending also large amounts of resources just for STORING energy.
And then Bitcoin comes and fix all of these problems: Bitcoin is pure storage for energy, secured by mathematical algorithms, something that will be eternal. If you own Bitcoin YOU OWN ENERGY FOR THE REST OF YOUR LIFE.
So, in order to live, humans must spend energy, but now with Bitcoin they can spend it wisely, only for things they really need and when is needed.
