Siacoin should be renamed to something that is easily relatable to file storage (eg. filecoin). I have heard about Siacoin for a long time and used to think that it's just another shit coin only good for mining. I have a strong feeling that newcomers to the crypto community have no clue of the purpose of Siacoin.
One more suggestion- Siacoin should make it easy for people not familiar with crypto wallets to easily purchase Siacoin using their credit cards and use their service. Right now people have to make a new wallet -> then register on an exchange ->buy siacoin -> withdraw (and paying a withdrawal fee)-> Go to Siacoin website and buy the service. All these procedures combine to form a very unappealing experience.
