I'm aware there are many new security token projects nowdays. As far as i know, security tokens are hard to get listed on exchange because of regulation of some countries. Big exchanges would rather not to list security token than getting banned from some countries.
Blocktrade or Dx.Exchange is already operating. Blocktrade has MiFid II license which allows them to trade tokenized securities. CHX (WeOwn) will also go live this Q1 which will make tokenizing shares/securities quite simpler so that exchanging STO would become much easier. I'm sure those big exchanges will pursue the license if they want to stay in the game.
STO is not that good. There are only few projects that can fully operate and make profit. It means only few projects are worth it to put your money as company share (security tokens) and get dividend. It also means that capital gain is overall better than dividend payment.
You're looking it the wrong way. Compared to most ICOs, STO is way better because it guarantees investor that they can have profits/dividends. I believe most investors will be happy for that even though the number of STO is small because in the end they only care about profit.
By the way, what is disadvantage of KYC for bounty hunter? Did they have posibility use our data for bad thing?
Of course, it's possible. How can you make sure that your data is not sold in the black market? KYC is a double-edged sword.
How about project who have starting ICO in exchange platform? Such as LATOKEN.. Did they have more succeed percentage comparing with regular ICO?
No, where you do your token sales doesn't have any guarantee that your project will be successful (in terms of price too). Even if it can pump the price, it won't last long.
