Security tokens will not have much effect on cryptocurrency, it makes the same tokens as ICO, even though it is STO, the effect is only on legality, but if the project is without development, what's the difference with the scam project? it's the same
Good point. It all depends on the specific company's vision in other to increase the adoption of its token within the mainstream world. If there's no development, innovation, or real use cases for the world, then I'm afraid STOs will fail the same way as ICOs did back in 2017. Still though, we cannot deny that STOs are much more regulated than ICOs. In this regard, companies are obliged to fulfil their promises within the tokens they've issued or they'll face fines from the government itself. With ample regulation of the crypto/Blockchain industry, there's a possibility that STOs could become the next big thing in the mainstream world. If successful, STOs could replace traditional IPOs as we know them.
But I'd say that it will take a long time before STOs are widely adopted by mainstream businesses, companies, and investors alike. After all, most Blockchains lack scalability which is something that needs to be addressed ASAP to increase adoption worldwide. Without a scalable blockchain network, companies won't be able to issue tokens across investors worldwide with ease. Luckily, the Ethereum development team is working on a solution for this. Sooner or later, the ETH blockchain will become scalable enough to make STOs practical within the mainstream world. While there are other competitors which are much more scalable than Ethereum (Tron, EOS, Cardano, etc.), they aren't as trusted and recognized within the business sector as the world's second-largest cryptocurrency by market cap (ETH) is.
Nonetheless, STOs could be the next big thing in crypto right after Blockchains become more scalable for the whole world to use. Right now, many people are waiting for Bitcoin's halving to take place in May 2020. On the other hand, crypto enthusiasts are anxious to see Ethereum take the next big step in upgrading from PoW to PoS. If all these events take place at the same time this year, then we could experience a "boom" in the Blockchain industry like never before. Hence, BTC's halving event and Ethereum's Casper PoS upgrade will be the next big thing to happen in crypto land soon. Just my thoughts
