Cardano is among the biggest coins; however, it has such a low ratio of staked tokens "in Dapps" due to a lack of protocols. Now, before I go any further, I must make it clear that ADA staking ratio is low or looks low because ADA is actually staked by delegation and does not leave users' wallets. So my claim here is not about the ratio of ADA staked by delegation, which actually has a decent ratio (appx 75% as of April, 2022). However, staking by delegation (appx. 5% APR) is not attractive enough for everyone, and it still does not lock enough ADA to create buy pressure. In other words, there are still many ADA holders who simply keep their tokens in their wallets or on exchanges; and when these users cannot make desired profits, they are likely to create a sell pressure. If Ravcube can offer a safe protocol with better APR, it can trigger a new wave of protocols to appear on Milkomeda and exponentially increase the TVL of ADA, which would translate to a higher ADA price.
Please, check the the image below to see the immense difference of staked tokens (Mcap/TVL) between Cardano and other big chains. Any decrease in Cardano's Mcap/TVL (133.9 as of April 23) will increase the price of Cardano and bring value to both Cardano and Ravcube investors.
