I found the solution, here it is:

I had to create a shortcut, and add in the "Target" field the following: -datadir=C:\Bitcoin, for the "Bitcoin" and -datadir=C:\Bitcoin 2 for the "Bitcoin 2" installation.

I had in fact read about this command, but at first I tried in the debug console, which did not work. I tried the above solution and it worked.

Hello,

I would like to run at the same two Bitcoin Core instances.

I had in the idea to store both of them in a two separated folders located directly in the C:// directory.
This for both ease of clarity and portability.
I say portability because I would like to host both the executable file in this folder and the blockchain data, as well as the wallet and the configuration files.

I first created two folders in in the C:// directory : "Bitcoin" and "Bitcoin 2".

I launched BitcoinCore.exe and it asked me where I want to install Bitcoin. I chose the "Bitcoin" folder.
I launched and quitted immediately.

I moved Bitcoin to somewhere else so that when I launch a second time BitcoinCore.exe it asks me a second time where I want to install it.
This time I chose "Bitcoin 2" and quitted again.

I moved back "Bitcoin" to the C:// directory.

I now have "Bitcoin" and "Bitcoin 2" both with a .exe, a wallet.dat in it, and the very very beginning of the chain downloaded too.

Problem is that when I started bitcoin-qt.exe from "Bitcoin", it loaded the "Bitcoin 2" files.
I know this because I looked to the "Information" tab.

What to do to be able to have two Bitcoin Core instances running at the same time, each having its own folder with anything needed in it?

Any help would be greatly appreciated!

Not really!

But this is partially my fault, I was not precise enough. I am talking about the regular Qt wallets.

I would like precise figures because I have spare computers and I would like to dedicate one to host wallets.
However one is way more powerful than the other.
Hence I would prefer to use the weaker one - but still equipped with an i5 CPU and 8 GB of RAM - to keep the other one for an other purpose.
But to know for which one I should go for, I need to know if the 30+ wallets that will be running on it will not weigh too much for the weaker computer.

Well, I do not consider ERC20 tokens as altcoins for the simple reason that they are tokens and not coins!

But anyway, I was referring to desktop wallets.

You are probably right.

I have seen some times blockchain data file available for downloading, so that might be a solution?

Because the case is that I just ordered the external disc drive, and I am a bit impatient you see!

What do you think about downloading the blockchain database and just make a new install on the external disc drive and add the already-downloaded database to the new installation folder?

Yes, to make it really safe I will of course keep my private keys elsewhere.

Yes, of course.
Keeping the wallet.dat did not came immediately to my mind, but for sure I will do it too!

Hello everyone,

What is the average load of an altcoin wallet, in term of computing power and memory?

Thank you!

Great thank you!

And what about downloading it on my laptop for now and then moving it to the external disc drive?

Hello everyone,

I was wondering if it would be advisable - because I know it can be achieved without much trouble - do host the wallet files on an external disc drive.

Will it stress particularly the disc drive in question?

Will there be any latency due to this?

Thank you for considering my questions!

I do think so. It would only be a threefold increase in value, and after a year like the one we just had, it now seems incredibly feasible, at any moment. I do believe that we will see this kind of price before the end of the year, I am sure of it.

For me it is a total blackout. Except myself and a few people I met here on Bitcointalk, I never saw anyone even knowing properly what is Bitcoin before I told them. So the impact over our economy is absolutely inexistant, and here lies the potential : catching daily trade.

There is no reason that it would redistribute wealth, really. Even if price increases, it increases the same for everyone, so it changes nothing. Rich people may however be more prone to invest, but I am not sure rich kids are really more in the game than College professors.

Forget about the authorities. A friend of mine got stolen for the 15th time - no joke ! - and since in the 14 previous times police did nothing, he did not even bothered to report it, since all they do with it is statistics, even probably biased. This is to say that in life, if you lose something, Bitcoin or not, you can only count on yourself. But Bitcoin is safe enough so it should never happen if you are cautious enough.

Well if there is no one to buy, it means there is no one to buy what people are selling, so price will simply be stagnant, nothing more. But it is useless to damage your brain with 'if' when such a possicility is sure to never happen.

This is because medias are owned by people from the old system, such as stock investors, bankers, etc. Bitcoin is indeed a threat to their financial supremacy, so they do all they can to shot it down, not very successfully for now !

We have here an anti-Bitcoin from what I see ; in the last three thread I went you were too and criticising Bitcoin. It is false, there are many people much more wealthy than you two - or maybe just you because you are probably the two same people - that are hodling Bitcoin. Prove me that I am wrong and I will accept to change my mind. I am waiting your proof !

Well I was excepting the traditionnal rumours on China and Russia but instead found something else, rather... funny. This is not to be offensive, but those five countries are everything but of a big weight in world economy, so this is not big news.

You are a week too late with your blatantly fake news ! For your information, Bitcoin price is clearly recovering, with a strong resistance at 8000$, so what you are saying is just pure smoke.

Wow, I love your story bro, very interesting and quite true ! I bookmarked it to read it again in one year or two when we will have reached MOON MOON LAND !
