Regarding TX fees, is it really such a huge problem? It's barely used as a currency as of now.
There are scaling solutions obviously so in the future, it's not a worry.
People see Bitcoin more as a store of value, for them higher fee's is not a major problem. Of course that needs to be fixed for lower tx.
Then people are wrong - the chain that succeeds will be the one with the most utility, focusing on store of value will see Bitcoin replaced by a younger fitter prettier model.
Store of value is all that matters for the forseeable future. Bitcoin will not be replaced in our lifetime. If Bitcoin does not "succeed" then you can be sure that no other chain will replace it, the concept of crypto currency will have failed. The best that any alt coin can hope for is to fill a specific niche.
Sorry to rain on you but have to disagree, this is bitcoin/blockchain and things move quickly, if Bitcoin doesn't develop and evolve and add utility to its bag of tricks it will be replaced just like any other organism or technology. Bitcoin % of market cap is below 50% and the trend is one way at the moment. How much importance will people place on Bitcoin as a store of value when it's <30%, <20%, <10%? The money goes through Bitcoin to other crypto at the moment, but the bulk of new money is going to other coins right now because they have the usecase propositions not Bitcoin. One upside is that the big gainer of the last few days is cripple, and that tells us that the people investing don't understand the difference between a distributed and a decentralised ledger and still think a walled garden is a viable proposition on the internet.
Bitcoin is battle-tested. No other coin even comes close to the security Bitcoin provides. The problems Bitcoin is currently facing would be just the same for any other coin. Bitcoin's slow (and cautious) progress is a
feature, not a bug. The current financial system cannot, and should not, be replaced quickly. And ultimately, anything that most alts can do, will be possible on the Bitcoin blockchain via Lightning, Rootstock, Sidechains, etc.
I wish no bad luck on anyone, but I worry that those people throwing money at alt coins are going to get burned hard. As the incentive to attack those chains increases, you can be sure that people are going to start trying.
