I agree, every coin I've ever purchased that has dipped has eventually risen back past where I bought it. It took a long time for some, so you could argue that I lost money by having my money trapped in a coin and thus couldn't further trade with it, but I refuse to sell when not in profit. That said, I will sell if the price is dropping significantly purely with the intention to buy back in with the same amount of money and getting more coins. You can make money in any market, but patience is absolutely the key to it all.
Good strategy. Being a Bitcoin user, you must have patience at all times. Your patience and sacrifices is worth it because as time goes by, blessings come. But patience is not enough, you don't only wait for your luck to come, you should always find a way to recieve what you want. Being patient on what you do will give you good results on your future days. Never lose hope, pray and take an action on the things you love.
