Me, i can't afford to buy Bitcoin these days. The price is very expensive right now. What im doing is i buy some altcoins and sell it for bitcoin when they pump. That's the easy way to earn more bitcoin because altcoins are cheaper than bitcoin. But if i have a huge capital. I would buy some of Bitcoin for my long term investment.
If you cant afford to buy whole bitcoin just buy a piece on it and time to time if you have extra money just invest it in bitcoin that is what i am doing. I list my money and the current value to monitor if my investment is gaining some profit.
Very accurate about how your work is, that is how a trader works. Bitcoin soared, and now it starts to decline, this is the opportunity to do business for everyone who has the ability to look at the market. good luck.
