I don't really have a strategy that I use. I just buy some Bitcoins every now and then when the price has gone down to hold for the long term. That's all I do at the moment. I am not even trading. It's purely holding what I do. I am so happy with my Bitcoin investment that I never look into any other investment. Bitcoin is more than enough for me as I believe in its full future potential.
About investing. Dont have any strategies because honestly i didnt know how to invest here. What ive only know about investing is that you are buying some bitcoins wherein you will deposit that bitcoin here in some particular ICOs. And when that signature campaign reached their hard cap or even their soft cap. Maybe the value that you deposited in to that campaign will be doubled or being tripled.
