I believe in the old solid coins more than the new ones. I mean, those that are moving forward with the development of their technology. Siacoin (SC) is of course one of them. Although they are facing new and innovative coins right now, they cannot be kicked out from the top 100 because they have already built a strong community of satisfied cloud storage users and investors through the years. I can even categorize Siacoin (SC) with Ethereum (ETH), Stellar (XLM), etc.
