First of all, as stated often online: don’t take financial advise from online strangers, but do your own research. I would suggest taking a look at the Sia project itself and their ideas about data storage. If you believe this technology is solid and will become a future asset, then invest. I did, now the price is low and there is still a lot of room to grow but only with the money I am willing to lose. There is no quick win in investment that is not completely unrational and risky.
As always: check the developers background, their idea, their plan and business model, the predictions online, the growth cycle so far and establish a clear plan for yourself when to buy and sell a certain coin
