In the event that I were you, I'd pick ETH Grin. In spite of the fact that BTC is the lord of crypto world yet I feel like ETH superior to BTC, at first due to exchange finishing velocity of ETH is substantially quicker than BTC, ETH exchange charge is likewise much lower than BTC. Next to ETH blockchain is being utilized to build up a considerable measure of new tokens from new ICO extends so while this year is the time of ICO so I think in this year, holding ETH is vastly improved than BTC Grin
