I would like to add some more precious things as not just buying and holding Bitcoin for 10+ years rather switching it to the right cryptocurrency timely to get much higher returns on occupied assets in the real world. As for now, we are seeing many altcoins already jumped like a skyrocket boost. Investing in such valuable coins can also make anyone, not just a millionaire even a billionaire or trillionaire.
Still crypto is the initial phase, and since it comes to market, it has opened many new doors with new dimensions of business. Nowadays Defi, NFT, LP, Minting, Staking are on the fly. And in the coming future, there will be definitely a new era of the decentralized world that will explore new business models to the world.
