They can make an altcoin and voila, they'll have a blockchain.
But there's no stronger blockchain than Bitcoin's. And if that's advertised enough, organizations will come for the blockchain and will have to use bitcoin for that.
why bitcoin blockchain is safer than monero blockchain?
The network security behind bitcoin is 360,540,831.57 GH/s, that is a lot more than monero and that is why it is safer.
only because it has more users NOW. but in the future...
Dude this is why someone asked if monero should be censored on this forum because you guys are like cultist, MONERO WILL NEVER OVERTAKE BITCOIN. You can think I am crazy all you want but let me tell you I think you're crazy. Just look at the increase in hashrate per month at both coins and tell me which number is bigger.
Yeah, thats what Monero fanboys (or some of them) seem to not get. Monero will never be as big (let alone bigger, lol) than Bitcoin. Why? its simple, its super anonymous-only features give no chances at being transparent. This kills a large base of users and uses. Plus Bitcoin is king in all that matters: network strenght, adoption, network effect in general... which is all that matters, even more than who has got the best-ever technology.
