Bitcoin has now gained credibility and acceptance among people around the world, almost every altcoin in the crypto market follows the direction of Bitcoin, especially, when the price of Bitcoin fluctuates, most altcoins also fluctuate at the same speed. And that is why Bitcoin is considered the king of crypto.
There are also many altcoins that are a kind of scam, they often do not survive in the long term and sometimes cause big losses for investors.
In the context of Bitcoin's history and technology, it is really proven that Bitcoin is a safer and more reliable currency for long-term investment, which never disappoints anyone in the long run, Or it is very unlikely to disappoint a investor in the long run holding.
Above all, a detailed analysis and good research are essential to invest in the crypto market. Instead of misleading promises, investing in a popular, widely accepted, and established currency like King Bitcoin provides investors with security and the potential for greater returns.
My only option to invest is Bitcoin nothing else. If alts have to follow the pattern of Bitcoin and have short life then why not go for Bitcoin only, why taking chance of investing in alts whose next week fate is not clear. Today Bitcoin difficulty is at it's ATH, which means that now it require more computational power to mine the same number of blocks and this makes the network secure against attacks. This feature is intrinsic to Bitcoin only. No network is so much secure and decentralised then Bitcoin.
