I don't know, it seems they are too cheap now, i think it is time to buy some siacoin and sell them later.
I invested in SiaCoin when the price was at @750 now the price is below @500 which hurts me a lot saying the truth, I believe that siacoin will rise later this month (because I invested ) but the price started to get dumped from Day 1 when "they" introduced the Asics, maybe they are mining now and dumping the price?
Loosing 1/3 of the investment hurts for sure. But you bought on a very, very high level, and maybe this was the right lesson to learn for you, not buying on peaks again, not buying after a x25 rise ...
In my opinion, SC will recover and rise further on. Decentralized storage will be the future for everyone, who won't give his private data into the hands of big, non transparent companies. And Sia is the best competitor on the market by now, with a trustworthy team of developers. The asic will be delivered in march 2018 - as far as I know. So noone is able to mine SCs with it now. I think that the actual drop is a consequence of cashing out profits from the last month, combined with panic sells of the ones which came in too late, combined with a subliminal feeling of uncertainty.
I can't - and I won't - advise anything to others.
But if I where in your position, I would hold the coins.
We never know when a coin is going to get dumped or pumped, so do I, I thought that at that time SC is going to reach 1k so I was ethinking that it's a good time to buy and sell at 1k later but that still didn't happend, but if within a month the price gets doubled (now to 1k) then It's not a problem for me.
Right now is a bad time to invest in crypto for quick profit, so if your intention is X2 quick, forget about it.
BUT, for long term (1-2 years+) it is still a good time to invest. Best advice I can give you now is with a good project like this one, put your coins in a safe place and just forget it for quite some time, you will gain much more this way.
I definitely agree with you on this, I think now is not really the right time to invest and gain profits. But for long term yes, this would be the right time to buy altcoins because the prices are its lowest and just leave them for a couple of years. At least that's what I'm doing though.
