Siacoin is undervalued a lot.
Siacoin performance is just starting to raise from ground.
Siacoin is a potential competitor to DropBox, being safer, cheaper and more future proof.
DropBox, nowadays, is worth 3.5 Billion dollars.
The siacoin project was launched 2 years ago. There is no way a decentralized peer-to-peer network for computer storage reached peak after just 2 years.
Siacoin (SC) is unoptimized yet, and has more space to improvement.
If you ask me if Siacoin is worth mining right now, i鈥檇 say no. You can get $1.5 daily revenue from a GTX 970 (A GTX970 can mine around 2000 Siacoins per week), not taking in consideration daily electricity expenses and GPU鈥檚 lifetime.
But if you decide to mine Siacoin as an investment, long term, it would be extremely profitable as people would be looking for more protected methods to store files, archives, data.
