I just left it in the wallet until it increased again.

Good idea.. but what if butcoin will not increase its price again and it continue to go down and down and dont have any chance to go up again?
Do you think miners and bitcoiners will let this happen? I don't think so. bitcoin will never drop like this and don't reach to 1$ per bitcoins..
I wish if it could get 1$ again then may be i will buy 500BTC atleast . I could not arrange more or would have bought 1000BTC and then wait and hope it reach the todays price again in some years and i would be millionarie.Oh man this is all just a dream
Just sell one bitcoin today and wait for that day when bitcoin dropped to 1$ (which will never come) and buy 600 bitcoins with your one bitcoin's money. lolzz
you will surely become millionaire when bitcoin again reach to 1000$.
but if you sell your bitcoin and wait for price drop and price suddenly up to 1000$ to 2000$ then blame your self not me.
