In case of money related services, every computer wants to have maximum security protection from the potential hackers.

Due to the disincentives in the PoW system, it becomes unattractive to bad actors and has exited. Attacking a PoW network is not cheap, and one might end up spending more than he can steal.

The PoS algorithm needs better protection as it is cheaper to attack. The deposits of the validities serve as collateral, and if they go against the rules and create an invalid block, they will lose their deposit. Both are pretty much safe to be used.

But the PoS system still has the upper hand due to the collateral involved.

The Cardano project, my opinion, has great potential and will demonstrate its capabilities next year. At the moment, most modern designs of cryptomarket are based on a second generation blockchain. Developers Cardano took a step forward and developed the key elements of the blockchain, which is already attributed to the third generation of blockchain.

It looks like another improved blockbuster platform was released and I came across the project information. I found behind the project a very large team but I still can't come to a conclusion. I will continue to monitor the project for accurate information

I like both XMR and ETH, for me they are at the moment the only alternatives to BTC worth of investing and long term hodling without permanent fear of total loss like in some other short lived fantasy-crypto projects. XMR has the potential to enable cryptousers with options we always hoped BTC would do. I say "potential".

Another point for Dash that it will have a decentralised budget funds system in place that will make sure that future projects
will get funded though Dash's blockchain (it will be implemented with next update).

In my eyes this will mean that Dash as project can keep developing itself and does not risk drying up due to lack of funding.
This in contrast to other altcoins (and Bitcoin) who really need funds, any funds to keep operating. This (again in my eyes) increases the
surviveability of Dash as coin and keeps the community involved (which is rather large and active already).

Why you compare Bitcoin to Dash? They are very different and Bitcoin will alway win against altcoins because Bicoin is more popular and widery accepted by a lot of people. In my opinion, you should compare Dash and Monero or Zcash because they offer anonymous transactions and those are altcoins. Anyway both of them are great coins but I think Bitcoin will win because Bitcoin dont have premine like Dash so it is more legit.

For me Litecoin like Bitcoin is a future coin, a coin which will be with us in the future.
We all know bitcoin is being used more as a store of value and is being 'spent' less.
Litecoin will be the spendable coin.

I compare bitcoin and litecoin to Gold and FIAT. We dont go to a shop to buy goods
with Gold we use FIAT same with Bitcoin and Litecoin, Litecoin will be the spendable
coin IMO.

You said this was for the future. So I will assume that means years and not months or weeks. If that was the case, then you made a good choice. Litecoin has experienced amazing runs this year, but not so high that you feel it is over. It is always ahead even of Bitcoin in development, but that is the natural case for Litecoin as everyone knows it is a testing ground for technology like Segwit and even now Lightning network. Charlie Lee is the lead dev and so active to promote it.
