Anyway you look at altcoins, they are all disappointment. But still, we need to keep looking them in different ways.
Ethereum and other popular alts have not reached their all time high or not rose in comparison similar to bitcoin. But what we should also consider is altcoins are not bitcoin, they have their own use case and the price change similar to bitcoin could have an adverse effect on it's use.
They only have hypothetical
advertised use-cases, and serious investors understand that and avoid them. This is the reason why institutional investors are picking Bitcoin over any altcoin.
I don't agree with the opinion that holding long-term altcoins will lose our money. Because there are several altcoins that
are great for long term investment, so if you want to invest in altcoins you have to be able to choose the right altcoins.
My advice is to choose altcoins that have high volume, and are also popular, this will make them recover very quickly
if the price drops. But don't compare it to Bitcoin which recovers very quickly, altcoins recovery is relatively longer.
This is a poor advice, volume and popularity don't guarantee that a recovery will happen, there's no connection here. Also, the point of long-term investing isn't recovering from losses, the point is having high returns, and altcoins have no reason to yield high returns over long time - for that to happen, they would first need to actually deliver on their promises, and even here they fail. Take Ethereum for example - who uses it as a "world computer"? Ethereum team promised that everything will be moved to smart contract and centralized system will be abandoned, but the only thing ETH achieved is an ecosystem of tokens, which are mostly used for scamming.
