Good question ...
I'm all in on ALTs ... holding zero bitcoin ... switched my holdings on Friday the 13th
reason:
my end goal is accumulation of BTC , I care nothing of the USD valuation of any of the cryptocurrencies. The goal is accumulation of BTC, and my strategy is to maximise my BTC holdings by leveraging on this spread difference (that is ALTs are lower, BTC is high at the moment)
Bitcoin GOLD: the lack of "replay protection" is a real concern, no news from dev. team. why do we need Gold? by not holding any BTCs when the fork happens I'm hedging against any issues with the fork .. (I don't care for bitcoin gold ... thanks, but no thanks)
I'm betting that the spread difference between the ALTs to BTC will shrink post fork, and the speed this happens to outpace any benefit gained from the "free" tokens.
