Bnb definitely can go as high as $1,500 but $10,000 for eth seem too speculative, I would say $5,000 to $6,000 depending on the nature of the market, what will drive the market to get to that peak price, although the market is always full of surprises, it is possible eth, bnb and some major coins can perform even better than what we are speculating right now, but one which is certain is, you can't go wrong to hold btc, eth, bnb for the nest bull market if that happens this year.
