Enjin is undervalued in my opinion because their marketcap is only $20M yet they are run by the biggest company in minecraft who are developing it very professionally. I see it easily reaching a marketcap of $200M in the next 2 months.
I invested in Enjin and i don't expect it to moon soon. A lot of work to launch the platform and to become known brand (like steam). It's a long term investment.
