The future of the Blockchain is not going to face its bottleneck because of many reasons, it’s primarily the technology behind the existence of cryptocurrency in this world.
My experience in the blockchain is mainly because of the QZKCoin and Stock market, before working on QZKCoin I have to understand the backbone of cryptocurrency, blockchain allows every transaction made by QZKCoin to store in its database.
In the stock market, I use blockchain to buy or sell stocks, and for investments, since 2019 I have been working in crypto trading as well.
