ICX is one of many alts that are currently printing new all time lows, entering into price discovery. $VET $MFT $SC $KEY are some other examples that are also printing all time lows. I wouldn't necessarily sell here, but you should be very careful when buying alts right now. There are some exceptions such as $GRIN $BEAM that are looking very strong at the moment and then there are some like $ZIL that look good compared to the rest. With BTC looking so strong at the moment, I would just hold btc and be patient with most alts. If there is an alt-season coming, remember it wont just happen over night. You will always have time to enter, and its much less risky if you wait for an uptrend confirmation. Patience pays!
