Exactly as a small trader or investor we can't buy One Bitcoin, and for this reason we can't take profit from Bitcoin holding. For this reason altcoin is best for buying and from altcoin profit we can buy Some amount Bitcoin satoshi for long time holding.
If you cannot buy 1 bitcoin, then this does not mean that you need to refuse to invest in this coin. You can regularly buy a small part of bitcoin every time you have free money. And perhaps when the price of bitcoin reaches its high at a certain time, you will become the owner of a whole bitcoin.
Well, many are now capitalizing on the business of NFT games and their launches, the business is risky, it consists of staying in the whitelist of the project and buying to later sell in the public sale, this has been one of the ways that many people even with 10USD have been able to make 100USD and from 100USD they have risen to 300, then 500 and so on until reaching 1BNB, all this under the BSC network.
This is obviously one way, there is the other more traditional one in investing in altcoins and waiting for the movement of BTC to be positive so that profits of x2, x3x4 are produced ... but for now my advice is to risk a little more and enter the NFT.
