I did not sold any altcoin, I even bought some top altcoins like NEO, XRP, LTC, TRX, ONT, EOS. I believe this is just a plan by whales to collect tokens from weak-hands. It's good that I was able to reassure my friends who were desperate to sell tokens because they believed the bullrun was over.
Maybe the bullrun is over for BTC but not over for Altcoins.
