It seems that ADA’s value has been slowly decreasing against BTC, so much so that 1% BTC bleed causes 5% ADA drop. Why is this happening ?
This happens with all the alt coins. If you go to https://www.livecoinwatch.com/ and enable the 7day and 30d vs base percentage changes (under the layout button) you will see that most coins have seen a higher downturn than BTC. Also the newer and more risky coins (Ada is in this category) have often been hit harder than others. EOS is an exception, but that has been the subject of large amounts of wash trading.
