Siacoin is one of the best cryptocurrency. Siacoin uses the Blockchain and PoW mechanism, suitable as a long-term investment.
I think if you invest in SC, then you should buy more. 100,000 minimum. Why is that? If you only have a few coins with a low price, then the coins that you have the same will not produce anything for your investment. Whereas you have to wait a long time to increase the price in 1 satoshi. These coins are only profitable if you want to make long-term investments. Not for trading.
Siacoin is only suitable for long-term investment.. cloud storage has a good market in the future, today big names still dominate the cloud storage market (Amazon, Google, and others), in theory, I am very sure that Sia will succeed in the next few decades.
