Bitcoin is actually the closest to solving the scaling problem, because it has Lightning Network and while it is not yer released officially, people already use it on mainnet. Ethereum's scaling solutions are in much earlier stages of development, and other cryptocurrencies that claim to have solved scaling are so centralized that we shouldn't view them as competitors of Bitcoin - they are entirely different products with different value proposition. This is one of the reasons why Bitcoin is doing so well and altcoins don't.
load of shit information from you.
Lightning Network dosent solve scaling problem and its all over the web.
ethereum want to use ghost protocol which i speakd about to scale but it far away from truly be scalable... when you say ethereum work on this, is so much general where is details, how and what you also just copty past what you read....they wanna use ghost protocol maybe to scale...some say they wont work on it...ethereum is far awy from be scaleable and if yes they found answer to what experts years search while other fall to hype and scam and mian stream bullshit which will not happen without solving this problem.
you answerr to much general like saying nix coin shit also work on scaling ,,but how and what as top experts know all this coins that say they can scale they truly scam while nano somehow not and itoa work on dag yet they didnt found answers to the weakness of dag protocol.
this is huge shit when you say :cryptocurrencies that claim to have solved scaling are so centralized that we shouldn't view them as competitors of Bitcoin.
because scaling can be done on decentralzied system and centralized its depend what the founders choose yet, with decentralized tech which is peer to peer money the problem scaling didnt solve as the most last lecture of mit experts talk heavily about this and how much fast it need to solved if we want to put out paypal and visa and others which is industry of 30 trillion.
yet peer to peer file sharing is scale easy because there is way and peer to peer money come from p2p file sharing mixed with cryptography...
bitcoin mining is operate by giants around the world, the smallest players are far away from be in the mining game and every expert know this,.
you also dont aware what you post and you didnt even read my post before here which talk
about dag protocol and spectre and phantom and other cool stuff which scale bitcoin but still far away from be real scaleable.
dude you also need to go to school with your general answers like this and this coin work on scaling while all the top experts around the wrold didnt find answer
