If you have followed Sia you may know that the recent price hike was all down to Yunbi (a large Chinese exchange) listing Siacoin next to a small selection of other alts. So, consider what will happen when 1.0 is launched (and it won't be an "experimental" launch; that is all part of 0.6.x development and testing).

I would say now is a good time to re-enter Sia. It is down that 53-54 sats and seems to have hit a resistance level there. I doubt it will go much lower.

Good luck on whatever path you choose!
