Personally I can say that knowledge in cryptocurrencies isn't very beneficial
I totally disagree with you on this and I will advise you change your mindset regarding knowledge because it is actually very important in any venture. There is a popular saying that "Ignorance is a disease" and as you know, ignorance is the absence of knowledge. Where will you start from if you have no knowledge of what you are getting yourself involved in? How can you even protect your assets without knowledge? In all you do, please don't downplay the importance of at least basical knowledge.
because ask yourself, why is bitcoin popular?
Bitcoin popularity is well deserved. Bitcoin is the reason we are here, it is the first and will always remain the best. It is not controlled by men on suit who have spent some money on marketing shit and looking for who to steal from. Bitcoin is just starting and will even get more popular.
And then compare possiblities of bitcoin to Monero.
There is no basis of comparison. I have not looked at Monero before and I do not plan to do that anytime soon.
Then there is an ethereum that offers a lot of features unlikely to Bitcoin but still bitcoin is number one currency. I can't actually understand it. I don't say that bitcoin is bad, no, it's great but I used to think that Monero and Ethereum had potential to surpass bitcoin. That's why I think that bitcoin hodling is more important than bitcoin knowledge.
Seems you are so soaked in shitcoins. The earlier to covert a good portion of your bag to Bitcoin, the better for you. Nothing beats Bitcoin for now.
