Assuming Bitcoin Cash is stable and is proven overtime... I'd go with Bitcoin Cash - because wasn't that the entire reason for the hard fork in the first place? The idea was to improve the time it takes to mine the coins based on the block size. This was done with the Bitcoin Cash software modification and now testing of the viability of the coin has ensued. Once the market makers feel confident and comfortable with Bitcoin cash and technical performance... it's game over and Bitcoin Cash goes to the moon.

Then again, the original Bitcoin is the original distruptor for Cryptocurrencies... so, I personally am not putting my eggs in one basket until the dust settles and the market speaks. Both coins will perform... it's just that one is going to make some folks far richer than the other.

The key is....

...to simply watch for the cracks in the bases. This is all you need to know to make money with Cryptocurrency.

Happens like this:

1. Base cracks
2. Panic ensues
3. Price drops... and drops... and hopfully drops more
4. Trader nibble in on first signs of price drop below base
5. As the price drops further, trader adds to the position
6. Price bounces and recovers from hardcore supporters
7. Trader sells for Profit
8. You are one happy Trader

This market is for making millionaires and it's ripe for the making... :)
