I don't have any strategy. There some people using the "HOLD" strategy but I am the opposite, i use the "SPEND" strategy  Because I spend everything I get. As it's easy to spend your bitcoin, specially with a debt card,  and as I always find something to buy , like a dress or shoes. I am hardly able to keep my BTC for a long time. Usually I keep until i have enough to buy something i want. I am like this in real life with fiat as well, spend spend spend !!
