Easy as that. Buy rumours sell facts. Always 0-5 days before release of new feature comes dump which continues unless event outperform market expectations. Will ada smart contract launch outperform market expectations? Hell no! Fun fact about ADA is that its "soon to launch" something for last 4 years. In 2017 they were just a promise without working product and user base in an environment where there was not many ETH competitions, its 2021 now and nothing changed. They are still just a promise without working product and user base. They did not achieve anything while whole crypto industry made a huge step forward. And now in 2021 they launch ... smart contracts .... damn even shitcoins outside of top 1000 CMC have smart contracts. That's what investors were waiting for last 4 years? I expect huge dump and launching smart contracts after 4 years is a perfect cash-out moment for every investor who trusted this shitcoin for 4 years.
