I was very supporting the idea of a currency not being printed by government and peer to peer transaction
so I fall in love with bitcoin
I think if this was the reason you fell in love with bitcoin then that reason still exists. It is still peer to peer electronic cash. Instead, If you fell in love during the 2017 bull run then these feelings maybe withdrawal symptoms from the recent <4K breakup. Lately, many of the 2017 newbies are feeling this way. Don't worry.
4- if you have a bitcoin you will not used as a money you will always want to keep either to sell it higher price or waiting till it reach you buying price to recover your loss
I wish I cloud have reached to this conclusion earlier
That again depends on you. Majority of the people in developing countries just don't have the kind of access to a developed p2p market to enable them to spend bitcoin. So they hold in the hope that all these rich westerners will again go crazy buying stuff in their free market and push the price up..
If you are in a country that allows you to use BTC for financial transactions, start a service with it. Sell stuff for BTC. You could easily do a lot if the conditions are right.
