This is not investment, it is trading. If you want to invest, you will need to leave the bitcoin for a long period of time without touching it at all, it can be a range of 6 months to many years. But if you think you want to trade futures, you need to first learn sport, you can lose all the money on future account in just few minutes or hours, I will advice you to learn it for months with little amount of money before you use more money on it because losses can result in the process of you looking for profit. I have 70% of my money on bitcoin while 30% are allocation to altcoins, bit this is holding not trading.
