I never buy Bitcoin, I just collect Bitcoin by work. I am still collecting until now, and I will still collect it anytime. I still have some Bitcoins and the numbers are small. So I have to collect more so that the amount of money I invest more and more I can get more profit. I wish Bitcoin could change my economy, I wish I could buy a house and make my family happy with Bitcoin. So I will still collect Bitcoin until whenever and until the price of Bitcoin is very high. Maybe when all my dreams have been achieved, I'll sell my Bitcoin. But I still wondering, is it possible for Bitcoin to double until $100,000 in the future ?
