Electroneum is one of the biggest shitcoins you can ever find. The only people talking nice about it are paid shills, so dont listen to them. Richard Ells have paid a ton of people to shill for this project.
The mobile miner is a joke. Their instant payment is only a guarantee that the payment have reached the blockchain but still need to be processed to finish the transaction. You have atleast 5 other crypto projects with real instant payments that take 1-5 seconds. You have atleast 3 different crypto credit cards that can do the same too.
They know shit about coding a blockchain and have done a million mistakes over the last year. Stay away from this shitcoin
