I think there is no negative effects on bitcoin if dash will reach the highest pick of success since bitcoin is the one that had a control over all cryptos.

Of course litecoin still at the third position compare to bitcoin as the leading crypto and eth as the leading alt. But this doesn't mean that investing in litecoin is no advisable and concerning investing it is just a matter of timing.

There are negative rumours about ripple side by side as it seems no bright hope of investors in it. Where do you see ripples future in 2023-2028?
Feel free to discuss with us.

It is just a rumour and nothing more, ripple has a potential to reach its another era of great success because its supporters is banks. Many don't like this idea because it is against the real purpose why blockchain was created, it is created to become decentralized. Well this doesn't matter, what matters most is the success and the future of cryptocurrencies may the next to fiat and fiat will become obsolete.

I am preferred to buy and hold ripple, I don't know yet about bitcoincash aside from being more expensive than ripple because for me it is important to choose crypto which you know than to another that you're not familiar.

I think no! Because eth is under the chain of btc that no matter what eth success it will always affected by bitcoin situation.
