Yes. I have Samsung laptop. It's a small laptop, but I think I can use it for my college life.

I missed one 0 lol
Nobody said you are ignorant

If you think this is the best thing for then Good for you because no one can decide for you what to do with your money or properties.

I hope you didn’t invest due to FOMO and i hope you are aware of the risk involved in cryptocurrency because it is not a get rich quick scheme. Also, hope you researched properly on the best choice of wallet and how to securely store and safeguard both your private key and your coins because you are responsible for them.

In case you haven’t this should be helpful to you

[General] Bitcoin Wallets - Which, what, why?

Your last statement worries me a little bit, selling a spare asset that depreciates over time to buy one that does the opposite is a good move, saving some of your money and keeping it in reserve is a good move too, but when investing in an asset you need to be completely convinced about what you are doing, because if you are not then this could easily make you to take a bad decision if we get to experiment a correction on the next months.

In the first place, it is his money. So whatever he will do with it, is up to him.
So long he is not blaming anyone for walking that path of going into this market.
Also, I am hoping he has other gadgets to do his online transactions and others.
Because if you have other alternatives, that's not a problem at all.
The value of laptop can easily go down, but the potential of btc is quite high but risky.

I hope you have other computers, laptops, devices to use.

0.006 BTC is not too much and you can work to have money for buying that amount of Bitcoin.

After selling your computer, buying bitcoin, where did you store it?

I hope you did not store it on a centralized exchange or an online account.
Reminder: do not keep your money in online accounts

Choose your Bitcoin wallets

I recommend Electrum wallet but verify what you download.

As this was a spare one and you still have another one to keep you updated and stay connected online I would say this is a good move as the value of Bitcoin will have appreciation wherein laptop or any other electronics will only have depreciation in it's value.

Until we have a backup we can do this but not foolish decisions like you have only one laptop but sold it for BTC.

Now, just hodl it until the peak of Bullrun which is speculated post halving in couple of months. It's more difficult to hodl BTC than acquiring one.

Well, even if we said that, it's too late. He already sold the computer; now I think he only has a smart phone for him to do cryptocurrency stuff, and I think I said in his last post that selling his computer is not a good option if he needs it for his studies or bitcoin investment. But yeah, he already did; now the problem is, how can he grow the fraction of bitcoin he has? I hope the OP knows how, because even if you don't have a regret now, if you didn't do well in bitcoin, then there might be a regret you will feel, but of course we don't want that to happen. I guess it's good luck for your investment journey. I hope you earn from investing in bitcoin and bring another computer for your reward.

Lastly, I think it's a better option if you don't sell your computer and just find a freelance job or sideline for your bitcoin investment, but I think you want to buy bitcoin immediately, so that's why your only option is selling your computer.

It seems that everyone is optimistic about the Bitcoin price and the forum got full with Bitcoin noobs posting meaningless forum threads.
OP, nobody gives a damn about what you sold and how many BTC you have bought. Just do your thing and good luck with your Bitcoin journey. This is a really tiny amount of BTC. Do you expect to become a millionaire overnight by making such "grandiose" Bitcoin investment?
Just keep HODLing your coins and don't panic, when the price crashes(it will crash sooner or later). Don't get involved into any "crypto investment" schemes offering your ridiculous profits and don't get involved into crypto day trading. If you keep this advice you will be fine.
