BTC, ETH do not have a great future - it will tell you any serious crypto-analyst.Both problems have a lot of problems. And a huge commission, and problems with synchronization, and high energy consumption.I would advise you to pay attention to Marìnecoìn.Now happens fair distribution (with proof of promotion), with the aim of expanding the community as much as possible. The project does not need your money (like bitcoin or etherium), but your abilities are needed.The reviving project is no longer dependent on miners (dev-less, self sustaining).Ahead of the coin awaits the development of the technology of the future - machine to machine, artificial intelligence.The coin is already traded on the home exchange, and is very cheap. But ahead of her predict an interesting value, despite rumors that in the past she was D&P.
