bitcoin does not really compete with other investments.
That doesn't make any sense.
first of all it is very different then the other so it is not really something you can compare.
Not all "the other". There are about 10-12 altcoins which are derived from bitcoin, something like Zetacoin. And YES you can compare between bitcoin and altcoins (apparently, you don't know what altcoin is). Altcoin is an abbreviation of bitcoin alternative, So how can't you compare something that is alternating with another?!
secondly bitcoin is not a company or something like this. nobody is in change and nobody is directly profiting. like gold bitcoin does not mind what happens with itself.
I got no clue what you are talking about here. Besides, bitcoin doesn't have a physical existence like gold, but a lot of features of bitcoin make it over the top if compared with gold. Simple link:
https://www.goldrepublic.com/news/gold-or-bitcoinsthere are people that are mining and/or trading gold or bitcoin and there are competing, but not bitcoin itself.
And why do you think they are competing over bitcoin while bitcoin (as you claim) "does not mind what happens with itself"?
two sportsmen can compete. see who can run faster. also two companies can compete. see who can sell more operating systems. like microsoft and apple. but in both cases there is someone in charge, someone deciding to compete and someone agreeing to the rules (see who can run faster or sell more).
if i say a sportsmen is competing with microsoft over who can bring more cake to the moon, you would declare it nonsense.
bitcoin, just like gold, can not compete, because there is nobody in charge, nobody who can decide to compete, nobody to agree on the rules of the competition. sure you can compare the usd price of bitcoin and gold and see who performed better. but was this the purpose of bitcoin? did satoshi say let us create something that will rise in the dollar value so it can be more valuable then gold?
and if you want to see bitcoin as investment, then i say that there is nothing else like bitcoin. you can let two companies compete, but you would not compare stocks with the real estate market and speak of a competition. bitcoin is a new class. the closest would be natural resources, but you pointed out correctly, that bitcoin is not physical.
whether or not bitcoin has a competitor within the crypto world is discussed in this thread, but i just accepted the premises of the poster i was answering.
oh one more thing. companies are mining bitcoin and gold. and they are competing against each other. someone is in charge of these, they decided to compete and the rule is to see who can mine more. the reason for this is to make a profit, but those companies are not the same as bitcoin itself.
