I am keeping myself busy in buying whenever I have money in my wallet, as I feel that this can be best investment for future which can give me best returns.
I am doing the same. I will buy whenever there is a big price dip. I believe the bitcoin price will rise in long term.
If the bitcoin price drops below $600, that will be good price to buy. I reckon the price will be over $1000 next year.
There is nothing sure with bitcoin, so its better to buy when you have required amount than waiting for decrease or increase of price.
