but in my opinion, nobody can cover the bitcoin price because I think, bitcoin is the parent of all the coins that have sprung up.
Yes it is. Look only at the market cap of Bitcoin and all other coins. if another altcoin want to beat Bitcoin, then it is necessary that the market cap of that coin will come above it and that is in the next year impossible.
If other cryptocurrency's price is gone up then their market capital also will increase. Am I right or wrong?
