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?
I see otherwise. because what I see Bitcoin's development increases rapidly when we hold it. so I am more confident to hold Bitcoin, especially in the long run. because the longer we hold it will be faster also its development and the price will be high in the future. so it's great to hold Bitcoin in the long run.
