Electroneum is a best project in crypto platform but cardano is a better than Electroneum so you should concentrate in cardano it will make huge profit. I don't prefer these kind of project because we should not predict it will be a successful project in next year. So if you invest in Ethereum surely it will make big success in next year. I think google also plan to remove the advertisement ban so really it will be a big impact on this month so as soon as possible by Ethereum you will be future millionaire.
