Siacoin growth is shrinking. this happens as we see it today.
yes agree with you. When i first bought sia its supply was near 22b and price @ 414 Sat and i have lost it all... some because of BTC price and also due to its supply which is over 30b now and counting. 
Sia use is growing and growing ... Dont set in your mind that the Sat price is the companys use graph !
Here are the October News of Sia Team

TAKE A LOOK AT THE Use Graph Size of total Contracts in the SIA Network ...
So I really think SIA is growing very well ....
As an investor it doesn't help me you know, if company is growing and me as investor is sinking. BTW what growth you are talking about? was it all about twitter/facebook/reddit? and some xyz joining the company
. How someone can justify company growth when price is sinking?In the end it is all about the price.
As a real investor you should buy and buy at any price 2017 - because every day people who mine get theyr coins from mining. A friend of mine makes 2000 Sias a week. I am too lazy to mine so I buy every month a amount to get the inflation out of the coin.
Be sure that mining 2021 isnt so easy so the price of the coin will go much much higher then these days.
I think you really dont understand that u invest in years not in month in the ALTCOINWORLD
I am so happy That I bought another 20k Sia for less then aprx. 60 USD lol ...
Dont cry for the falling price buy and be happy on other days.
Take a look at my posted links here they are again.

Dont forget to buy and buy because mining is easy this days. Take a look at the smart contracts rate from 2015 till now ... Thats the real investment not the Satoshi you have 2017
