you still made profits, dont worry
Yes im very disappointed with myself because i am late in this investment, i was informed lately with my friends regarding bitcoin investment, now my friends are lucky because they already have a money and earned more from it, but they said its not too late for me, they are willing to guide me regarding coin ang how to invest.
Sometimes it really happens but the best things you should do is don't sell all your coin just sell some of it .so when the market go down you can buy back more and if the market go up then you can sell the other half that hold.
