The market has returned strongly as if there has never been a breakup. The recent sell-off has probably lightened the load a lot.
P/S: As long as BTC.D hasn't returned to the 43% mark, just trust and play. The target for BTC.D to reach 50% will continue to be considered for the Altcoin market.
Exit Altcoin when BTC.D reaches the 43-45% area and Usdt.D reaches 2% is the best. Keep a close eye on the market to see how the situation develops.
