Elon Musk has never mentioned Cardano in the past, and now he is trolling it. This is big for ADA especially leading towards its Mary Hard Fork update.

Elon Musk changed his profile description, and he also changed his profile picture to that of a fork; he also spoke about pegging a dollar when ADA was around one dollar.
He started with trolling Bitcoin and Dogecoin. Now he has invested in both of them and bought 1.5 billion dollars worth of Bitcoin through Tesla, and the fact that he is mentioning Cardano is huge. He could just be starting his trolling, and soon he could be investing and talking about it more often.
The price of ADA is relatively stable, especially with the ongoing dip in the crypto space; it is ninety cents.
Elon Musk's trolling might influence the price of Cardano, and there is a possibility that we will break one dollar again, especially if we start to see the markets recover in general.
The Mary Hard Fork update will be coming this year on the first of March; this is a huge Hard Fork leading into the Goguen Mainnet, introducing smart contracts and the sorts.
Cardano is about to finish the final product, and once it does, hundreds of partnerships will be coming out of this, dozens of announcements coming in a few months. It may even get to the point where Coinbase and Paypal will add Cardano before the end of this year.
The Mary Hard Fork update is significant because, for the first time in Cardano's protocol history, users will finally be able to define their custom tokens through the multi-asset ledger and adding a new tier of functionality and utility to the Cardano blockchain.
This will draw more interest, and we are most probably going to be seeing a lot of cryptocurrency projects proceeding to create their custom tokens leading up to the Goguen Mainnet, which will introduce smart contracts.
Previously, we saw Binance BNB skyrocketing and appreciating five times its value in a very short period. It went up to about 350 dollars at the peak from about 50 dollars. It is currently above 200 dollars and still going high because Binance BNB is solving the current Ethereum gas problem, and Binance is also a huge platform.
As Cardano begins to roll out these new updates, we will probably start to see ADA surge up in market capitalization, depending on how many announcements they have.
