What strategy you use to trade bitcoin?
Buy it about 5 years ago, and wait.
It is not trading.It is called hoarding

Yes,it is not trading, if you hold your amount and wait the right time, i mean when price is increasing than you sell it. so it don't mean you have doing trading, i also hear mostly people are saying that they have investment, mean they are just saving their amount. so i can't understand its that mean trading or investment?
