We are in a bear market in cryptocurrencies for quite some while and I think that now is the time to start accumulating as many various coins as possible so you are ready for the next bull run.
Solid Platform
I think that STEEM is a very solid buy because steemit the platform that it is connected with is already working. Many cryptocurrencies do not have a working platform yet and they are still working on it.
Price
The price is at one of its lowest lows and it really is proper time to buy in or at least start thinking about it. It is tough to say when it will start going up and when it will stop going down because any altcoin's price can behave differently. Also the price depends mostly on the bitcoin price and as soon as that starts going up most of the altcoins will follow probably.
Bull run
In the next bull run there will definitely be more people trying to create similar platforms to this one and maybe there will be a newer and better platform which could potentialy replace it. Though I think that steemit will stay strong and will be improving faster than its competition.
Overall I am a huge supporter of this project and wish it the best luck because the better it will do the better will all of us do and that is the main reason why we are all supporting it.
