One advantage of buying BMNR and ETH-related ETFs is that you won't get liquidated with OTC leverage. Even if the price drops, you can gradually average down by buying the dip. If you're confident, you can open long contracts on exchanges at 42×× or 41××. Recent volatility is high, so pay attention to leverage and position sizing. For a steadier approach, grid trading works well as recent fluctuations are significant.$BitMine Immersion Tech(BMNR.US)$Proshares Ultra Ether ETF(ETHT.US)
