I can make an informed guess on how long it will take for ETHXBT to surpass Bitcoin in performance dramatically. The monthly chart indicates we could expect a major breakout only after May, or as a worst case scenario, July. There are two possible top targets, and an estimated time duration of the rally as well.
The targets are 0.095937 and 0.228555, with a rally that could last until February, 2018. I'm going to hold my positions as long term trades, and I'll continue to trade around them with margin, to make my holds risk free, and only risk part of my profit from holding the trades open all this time. I'd reccomend keeping a 50/50% weight with BTC, and perhaps if you want, investing small in some ICOs. or other alts along the way, but only with 1-5% positions at best. Focus on this and BTC, since the charts and fundamentals favor continued growth in them.
Good luck!
