After I started my Bitcoin holding journey a few months ago,
At that time, my close friend Sam! also have some capital he want to put away in cryptocurrency, and I advised him to buy Bitcoin instead of an altcoin. But instead of him to have a long-term potential mentality, he was looking for a quick profit so he filled up his portfolio with shitcoin, while I went in on a single portfolio of Bitcoin and when the unexpected of FTX hack happen the whole market in shamble and his altcoin portfolio have dropped above %800+ but my bitcoin holding still maintains some level of stability.
This gives me more confidence in Bitcoin and newbie who are looking for long-term holding should hold more bitcoin, in their private wallet to avoid exchange, but your knowledge to always have a good entry price.
Bitcoin is definitely the king, and altcoins and shitcoins are just its clones. And most of these altcoins have nothing to be proved in the end, because they eventually lose their value in the process. But for bitcoin, the longer you hold them, the bigger chances of higher returns. And as long as you keep your bitcoin portfolio in your hardware wallet, it will always give you higher level of security too.
