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.
If you really believe in the price that will be reaching $1000 again next year, then even right now is a great moment to start buying. There is no need to wait for something that might or might not happen, which is you anticipating on the price going sub $600.
