i think both coins are same at the moment just pump and dump and in the end only bag holders will there, so better avoid to make invest in both coins and buy bitcoin to take advantage drop of price.
How can you say both coins are the same.
Crave has been out 2 weeks and was pumped from the get go and now it will be dumped.
Shadow has been around for 8 months and has never been pumped or dumped. It has been the most stable altcoin investment I have ever made. And that is because is are no p&d groups behind Shadow like 95% of all the other coins.
If you think its somehow Shadows fault that Crave is being dumped then you really dont know how things work around here.
