There are currently 4 way to be part of the sia adventure. In this post I'm going to tell you which ones will give you the biggest profits. They all have one thing in common - they are concentrated around the siacoin.
1. Mine siacoins
You can mine siacoins relatively easy with a GPU or asic. The big problem here is the coming of the obelisks in 2018, that will dramatically increase the difficulty of the whole network, making profits somewhat harder to forecast. If you allready have an obelisk, are you then home-free? not really, the difficulty will still increase and turning your expensive electricity into only a few siacoins. The whole mining is going to be risky business.
2. Buy siacoins
Buy the coins with cool cash on an exchange. This way you are exposed to the technology right away without further gimmicks. You will then be the holder of sia, and can only hope they will increase in value.
3. Buy sia funds
Sia Funds will give you a certain percentage of the total transactions. There are only 10000 Sia Funds available, where the 8000 are reserved by Nebulus. Problem with Sia funds, is the supply is so low now, that the price is not fair.
4. Host files
A lot of people are hosting sia files with their spare harddrives. The problem here is that no matter what, you will never get more than $2-7 pr. TB pr. month. Even if the price of siacoins explodes to $1.00 you will still get the equivalent of $2-7 pr. TB/Month. So this is the worst idea to invest in sia as of right now.
My recomendation is clearly #2. If you buy yourself some siacoins right away, you are immediately exposed to the coming boom in decentralized cloud storage. When the price climbs due to demand, you will win. The people that host on the network will not find, because there will always be a ceiling of how much they can charge. Amazon/google/facebook/others are setting this ceiling, and its only getting lower and lower.
