I think the important thing about bitcoin is not the first coin in cryptocurrency but in network security. Bitcoin already proven secure and almost unhacked. Transaction data spread all around the world and hackers can not control or change the data. Thats why many people hold bitcoin for long term
Its true that bitcoin is much secure than any crypto that exist now. All the informations that bitcoin hacked before is misleading. Is just that the exchanges before got hacked not bitcoin until the bitcoin network still improving and get better than before. And soon it will change our financial system and people will accept and believe that bitcoin is a good storage of value than gold itself. It will be the digital gold and its price will skyrocket in no time. Buy and hodl bitcoin
Bitcoin is the most secure because it has the longest chain, it`s impossible to alter it, maybe if there is just one node, but there are many ones, only together they can change something, why there is so many forks, some people can`t agree and they go to separate way. That is basic of bitcoin, who wish to study it can find so many things online about nodes, chains, transactions, wallets, this is huge! But people still don`t make difference between centralized and decentralized systems, between mining and staking, and plus all that have their subsystems. I think the main benefit of cryptocurrencies are that you are your own boss, you can do what you wish, as long as you know how. Blockchain is a new world, and it`s being constantly upgraded, so we need to do the same, we need to learn a lot about new possibilities. That is the main advantage, you can be free much more than in any kind of centralized system, you can make your own destiny, again if you know how.
