bitcoin is not merely a leading coin.. it is the coin that set forth the standard, and the other various shitcoins are trying to emulate it or to proclaim that they are better, and maybe they are not really doing anything but figuring out a way to print their own coin to make founders and other early adopters rich in the style of various ponzi schemes.
So bitcoin is in another category. .to the extent that it cannot be replicated in ways that shitcoiners try to set forth as if it were actually possible.
Altcoins are created largely in order to make money on them, almost everyone understands this, but there will always be those who understand these risks, but will still try to make money on it, in the short term. I don’t see anything wrong with this if you understand what you are doing, when you need to buy and when to sell so as not to lose money, but if you do it without understanding, then it will be a bad idea.
I consider ETH to be different among the altcoins that we usually think about. But of course, Bitcoin seems to be the leading coin in the crypto space which allows a holder to earn a profit, unlike those project that looks promising, raising millions during pre-sale but has no substantial to continue growing. This is the reason why we become confident of accumulating Bitcoin despite the risk because of such profitability features that most altcoins don't have. Though I invested a few altcoins, still Bitcoin got huge chunks of my investment capital.
The entire market is moving behind Bitcoin, only from this it becomes clear who is in charge in this market. I remember a few years ago Ethereum was worth about $50, I admit at that time I thought that it would never get out, and I see no reason why it couldn’t fall so low again, despite all its improvements.
