Now think you have 1 btc and you convert it into BCH. Example for 1 BTC you get 10 BCH. Rate per bch is 0.1 BTC .
After some day if Bitcoin grow up, At the same time BCH also will grow up.
If bch rate grow 1.5 btc then you will have 1.5 BTC.
This is possible, but when BCH dumps to zero because it is a scam perpetrated by fraudsters, you would then have zero BTC, zero BCH and zero USD. What then?
using Bitcoin in the short term is also very capable of generating substantial profits. so it's great to have Bitcoin for trading and any other business that can be done in the short term. such as trading is also able to be relied upon as a source of short-term profit Bitcoin. so not only in the long run to use Bitcoin.
