Anytime can be the best time to invest with cryptocurrency but if you are not that big risk-taker then am suggest that you wait for a big dip. When Bitcoin reached $13,000 that could be a good time to buy some. Now, it is already in $15,000 but there is still a big possibility it can go down as we are nearing the end of the year. Though this is just my guess and am not a good fortune teller.

As to BitCoinCash, it is also good to invest some money in there. I am sure that it will also be growing continually as it is now marketed as the best alternative to Bitcoin with its ongoing scalability problem. You need to spread your eggs in many baskets too and there is actually no need to limit to just these two as certainly there are others also worth watching and trying. Anyway, good luck on your endeavor.
