Help comunity with computing power

[Eleking]

Hello dear forum friends and foes!
I'm new here, i'm new in concurrency, but that doesn't mean I don't want to help improve things in this field. I have heard many, lets say rumors, that you can contribute to community by being wallet node or something like that. I can't explain it mo precisely, so could you please guide me with right keywords and assistance.
Saddest part is that I do not have SUPER computing power, just on HP laptop, but positive thing is that I have unlimited and, in my opinion, high speed internet.

You must be talking about running a full node. Here is more information about the subject:

But yeah, generally, running a full node does contribute to the network. Bitcoin Core also happens to be one of the most secure desktop wallets available, and you get to broadcast your own transactions to boot. It has fairly low requirements apart from the hefty disk space required, so you should go for it if you could.

If you're going to run a full node, it is recommended to use an old laptop or a laptop solely used for this purpose so you can leverage its optimal storage power. That said, you don't need super computing power to contribute to the network! In addition to jseverson's resource, check out this step-by-step guide on how to set up your own node: https://99bitcoins.com/step-by-step-guide-firing-up-bitcoin-node/

Thank you for your time.
I have one more question, is there any cryptocurrency whichs effectiveness, speed, trust is somehow related to bandwidth speed?

There are none that I know of. Cryptocurrency, at its core, is just money. There's no reason why it should be dependent on bandwidth speed. If nothing else, their clients should work perfectly under the slowest of conditions.

In the off chance that you're referring to mining, however, you might be able to find something.

I would also be interested on this, if I can make some alt by lending band or hard drive it would be useful since I have excess of both.

There are coins what are mined with HDD.
Here is an post - https://bitcointalk.org/index.php?topic=1346886.0

If you want to learn more, search for these terms - Proof-of-space (PoSpace), also called proof-of-capacity (PoC). I didn't evaluate any of these but there is chia.net, SpaceMint, Burstcoin

Can I use a personal computer to mine now? There should be very little profit. Basically it is already the world of mining machines.

There used to be a coin that can be obtained using your bandwidth, but because of the limited high-speed internet available all over the world, it didn't end up too well for the coin and the devs. Also, not all high-speed internet plans nowadays are unlimited (which is a shame), so there's that.

On some low-difficulty altcoins which utilizes GPU power, yes you can, though there aren't that many coins that are virgins on GPU miners, so your chances of finding one is very slim. In order to get some kind of decent profit in mining, you must obtain at least two or three GPUs and mine whichever is profitable. It might not make you a lot of money but everyone has to start somewhere.
