I'm wondering who recognized bitcoin as the best coin in the world? Or is that just your opinion? You don't need to pass off your opinion as the opinion of all people. No, I don't mean to say bitcoin is bad. Bitcoin is definitely one of the best inventions of mankind, thanks to Satoshi Nakamoto. But I think it's wrong to make such an unsubstantiated claim about the best coin in the world.
Every person shares his opinion based on his experience may be the OP has gained lots of money due to bitcoin investment so its obvious that if something is beneficial for you and gives you money then you will appreciate it.
There is no doubt that beside bitcoin other coins and assets are also profitable but as greater achievement it offers to you there is no other coin like this. Some people will admire gold because gold will make them wealthy therefore we cannot say that what an OP said is false. Other coins are based on bitcoin and without bitcoin they have no existence so this can also be reason behind the statement what an OP stated.
You misunderstood me. I in no way want to belittle the importance of bitcoin in world history. All I meant to say is that the OP is making this claim on behalf of the entire community. If I were him, I would simply write that "I believe bitcoin is the best crypto coin in the world". And that's it.
