it was often very good to buy altz in early spring / spring time of the year. Often this period just before Chinese New Year ,was the best for altz shopping. As bitcoin always dips after NYE and alts follow last year i was buying xrp in this period. It did quite well later on in 2017. So for 2018 i will be buying these days some HVN - hive tokens, HDG - hedge tokens, ICN - iconomi tokens, TAAS tokens, some KCS and BNB. Always dyor.
