Do the price fluctuations this week matter in the long run?

So I’m super new to crypto, like I just started last week. I’ve always wanted to but now that I’m old enough and finally have a decent amount of my own money, I thought I would put some money into crypto knowing nothing other than “Bitcoin is worth a lot”.

So I’ve invested about 1,4K dollars spread over Bitcoin, Ether, Solana, Algorand, HBAR, XRP, Shiba, Doge, Jupiter, with my highest monetary investment on ALG HBAR XRP SOL.

Anyways, I invested a lot right before the surge on Sunday, and then didn’t sell because I thought it would keep going up. Then I bought some more when it dropped on Monday, but waking up today and I’m down around 200 dollars, since I bought a big chunk last night right before everything went down.

Disregarding how bad my strategy was and of course no one having the real answer, does it even matter if I bought when XRP, for example, was at 2,2 and now it going down? Selling now would be stupid right, as everything should rise in the long run?

I’m not sure if I should pull the plug on SOL and ETH and transfer during the dips now to others like XRP, since I’ve read around and that one seems most likely to explode.

I’m in it for the long run, however I have this tendency to keep checking changes and it’s making me crazy, especially when being down so much money already (haven’t sold anything yet).

Idk, just wanted to get the thoughts of some more experienced people. Maybe the question is dumb lol. Thx anyways!

(I am ok with losing this money, although I am a student and it would suck so much haha).
