I would be buying and am buying the crap out of the alt coins listed in BTC terms not USDT terms......Like buying gold vs. the Yen vs buying vs the dollar. XRP and ETH are flat to up in USDT terms.....ETH has gone up from 200 to 257 in 4 days but look at it in BTC terms.....getting crushed to support......millions will be made in a short time due to this anomaly.
Buy BTC regardless of price and then immediately flip into Alt Coins. When BTC falls these will rocket all based on the ratios.
Good luck and good trading.
