If the price of the Altcoin goes up, then the Bitcoin value will go up. The reason is that when the price of Bitcoin goes up, the price of Altcoin goes up as well.
If people start buying Altcoin more than today, the price of Bitcoin will go up as well.
If the price of Bitcoin goes up by 2021, it will be a record.
Am I right?
Sorry pal you lack a lot about how bitcoin/altcoin works, every single altcoins in crypto space depends entirely on bitcoin itself, if bitcoin loses its value all other coins will reevaluate and if bitcoin surge in value all other coins will increase in value, buying altcoins to make bitcoin rise is nonsense
