Why was there a two year downtrend in the first place?
My GUESS is that 2(?) years ago when the BitShares whitepaper/solid-project-info was released a large number of investors wanted to buy at the same time. 'Innovators' who see the potential in BitShares and wanted to get in on the ground floor.
A high-density of purchases at the same time pushes the price up. There are more buyers than there are sellers.
Traders then latch-on to the price rise, and scrape their profit off the general trend, giving the smaller price swings up/down.
Then after a few weeks/months all of the 'innovator types' that would be satisfied to invest on just documentation and an early stage product alone have finished buying.
Thus the price gradually decreases, with price swings on the way, caused by traders.
Since then, much of the work has been behind the scenes. If you didn't believe in the future success of bts 2 years ago, there hasn't been 'that much' of a reason to change your mind. It's all still technological developments rather than use-case development. Grandma's aren't using it, the liquidity is low, it's not the best exchange you could be using to trade. You can (currently) get better liquidity and higher margin at centralized exchanges.
The one aspect that bitshares DOES offer right now, is the ability to trade on an exchange trusting solely private/public key cryptography. Security. You can't get GOX'd.
How many average people are both 1) Interested in trading on a financial exchange?
2) Understand priv/pubkey technolology 3) Have spare time and cash to fiddle around with bitshares figuring out how to use it.
? I'd say not very many at all
BUT, there are lots of TRADERS who do have all those 3 things. Crypto-traders who currently rely on centralized exchanges. Why should they go through all the steps to switch to BitShares, only to find that there is far lower liquidity?
Why would a $20k poloniex trader move to bitshares to struggle to trade $100's at a time?
I believe that a 2 year downtrend
might be coming to an end because the volume on the DEX has been increasing a lot recently. I think due to btsbots. Allowing bts investors to "make the market" on the DEX. Which adds liquidity and makes bitshares more attractive to crypto-traders.
Price up 2 years ago: early innovators who see potential
Price up today: crypto-traders are attracted by the rise in volume on the DEX
MY OPINION AND NOTHING MORE
