That's very shallow approach. Luckily for many is a bit more than "buy cheap, hold and sell with profit".
If everyone applied that logic, bitcoin would be dead by now. Who would give a shit about the currency no one uses (everyone just hold, waiting for the right time to dump)?
thats correct. and you can always safe and spend coins at the same time
, you dont have to choose.also: the beauty of BTC is , that everyone on this planet can do what he wants with the BTC protocol.
