Currently, Bitcoin is valued at $11,826 and rising. Is this a good time to buy small chunks of Bitcoin, such as 0.1 or 0.2 BTC? On one hand, people buying now are buying very high. But what if it doesn't dip again to under $10,000 this year and just keeps going up?
No one knows how the price of bitcoins will change in the future. You need to make your own decisions. If you predict that the price of bitcoin won't go down, then you're going to buy bits now, and he's going to bring you revenue.
