Appcoins is a great coin, they have great customer based and they have VC founding which means they are establish to a certain extend.

Iota has great technology. With tangle with only needing 2 confirmations only, the scalability issue can be solved.

I have iota in my blockfoilo. As for Appcoins, i invested in Gifto instead. To me, Gifto is very similar to Appcoins in a lot of ways. Even though Appcoins dream is bigger, they are not effectively in reaching out to the crypto audience. Whereas, Gifto is able to create the hype and even have crypto influencers to talk about it. Nevertheless, I am still consider to get into Appcoins because they still have burning of token structure if ICO hardcap not reached.
