Stay away from bitcoin cash, when the coin was first released a great deal of the community was mad towards their developers because they called their coin the real bitcoin when it is nothing more but an altcoin, and yet people were deceived by this and they invested in the coin only to realize their mistake way too late, however despite of this there was a time in which the coin had some popularity and it was a top 10 coin, but that time has passed and now very few people care about it, so it is way more likely bitcoin cash keeps going down in the ranks than the chances we could see it growing up in value 17x in 4 years.
