Sia is the first data storage on the blockchain. It exists quite long. You can safely store data on the blockchain, against a very competative price. People can act as hosts to earn coins. You can easily earn 30k coins per year, using the overcapacity of your own computer. For a long time investments in Sia didnt seem to realize interesting profits. That is until recently. Sia act like a bullrun is full on the way already, and even made a 20% gain in a week where all altcoins went down 20%. So, this 'old' boy might be the new gem on the block.
All conditions seem to be ready to go to 4 cents, its ATH, which means investors have the chance to profit 5 times their money. After that, we will see, if it reaches beyond.
Today Sia is down a little. This might be a good buying opportunity.
