the most predictable ones are bitcoin and ethereum. both cryptos have a good future. everyone here agrees on this, because btc and eth are icons of the crypto market.
I disagree if you state that BTC and ETH futures are predictable. Although Bitcoin and Ethereum are crypto market icons, no one knows their future. We don't know how long BTC or ETH will survive in crypto market. They can be the best crypto coins now but no one can guarantee what's happening with BTC and ETH in the future. What we can guess is, BTC or ETH can survive a long time if we consider its popularity and its role in crypto space so far.
