Sorry for not responding before this spike in BTC. I think BTC was a great buy because it is an entry point for many new investors. This spike in BTC will be followed by altcoins very closely. I would diversify across a few that are meant for different purposes. For example, NANO was recently hit because of a theft of coins from the BitGrail. There is still some controversy there and the price can go lower but I think it is a buy under 9 dollars because of their DAG technology (IOTA too). ETH is still very low in comparison to the gains that BTC has made and ICX too.

ETH, ICX, IOTA, NANO
