We’re currently facing an issue with our main CMC page, displaying the old and deprecated token charts (running on the Ethereum and Arbitrum networks) instead of our new RISITA token chart (running on Base network).
Those charts look terrible and dead right now (although it’s the exact opposite!), because we had to dump the old tokens to re-create the liquidity on Uniswap – Base chain, and get our new market cap back to where it was (around $1.8M). If you want to know more about what we have done, please check this Medium article.
Anyway no worries amigos, we’ve submitted an application for an update, it’s just a matter of time before our pages get cleaner! 
Meanwhile, you can go directly to CoinGecko‘s page (or the CMC section of RISITA on Base) to get the correct history chart. If necessary, you can cross-check from other legit sources like DEXScreener or DEXTools!
