Do not expect a coin to go up everyday, do not expect the market to always be in one direction, the market is volaltile and fluctuate in both up and down direction.
So wich coins grow everyday ? There is no such a coins?
No coin grows everyday, but you can buy bitcoin, never mind during downturn, be happy and hold, the price will still reach ATH. If you want to hold, you can hold for years like 2 or 3 or more years.
The price of bitcoin reach $69000, buying and hold now at $42500 is not bad. But you can divide you investment capital into 3 or 4 so as the price 6if bitcoin decrease, you can invest more. When the price will increase, you will make profit. But this is a long term investment strategy.
And why nobody dont create the growth coin that will have large suplly but the supply will getting smaller by the time and coin never fall
Just like what ethereum implemented in a way certain amount of transaction fee in coin are burnt while the remaining are received by miners. There are also many other cryptocurrencies that have it but that does not mean the price of such coin will not decrease during bear market, but they are more deflationary if marketcap is constant, but marketcap can never constant, this can still make other coins with most adoption to increase more.
Just always remember that the constant devaluation of fiat makes this possible (bitcoin price to be increasing in long term) while also bitcoin adoption continues.
