Really? 10years ago, How I wished I knew bitcoin at that early time. Well, I guess you're right but at some point you can compare then and now. Everything is unpredictable. You cant be sure that when you buy now, after ten years the value will rise like now. Unlike planting trees that you are sure that it will go strong and bear fruits, bitcoin is volatile and that is the risk. It still depends on the stability of the market.
