The computer is a necessity in the current life, if you don't have use for it then go ahead and sell. But you will need some digital device to access your coins after you buy them.

Also I agree with @adaseb here. The things you can do using a computer to earn money should be kept in mind. You are exiting teenage now and you will need a computer for studies, work and research, so I don't find it to be a wise decision at all.

Best to talk to your parents and assess your financial and educational condition before taking this step. Bitcoin can wait but your education needs to be completed in time.

It entirely depends on your usage of computer. Personally I would like to keep the computer intact because I run a business from it. But if you are using your computer just to play a games and if you are not doing anything productive in your computer, then probably it is best for you to sell.

But let me tell you, $100 is a pretty decent amount in many other countries. A lot of people are unable to save even $50 a month. You are lucky that your father gives you such an amount of money, which corporate job freshers earn as their first salary.

It depends on you. If you don't use the computer, you can sell it to buy bitcoins.
But if you still use the computer for daily activities, you should not sell the computer.
You can still invest in bitcoin using $100 from your father and that is enough to invest in bitcoin using the DCA method.
But everything comes back to you because the decision is in your hands.

Selling your computer system may not be the accurate decision for now because you may still need the use of the computer system anytime sooner if you have bought your bitcoin already, knowing that things are now expensive you may also have no other means of buying one when you needed it most, i will suggest thst you make use of your monthly income to use some part of it to make an investment using DCA and you continue accumulating gradually from there as long as you're able to hold enough, you will be profitable about it.

If you have another computer I think that you can sell this particular you want to sell because right now even though you sell your computer to buy bitcoin you still need a computer to use to monitor your bitcoin, even you are in bitcointalk and you need a computer to use and write things in bitcointalk, so you selling you computer is not good, I can advice you to sell any other things but computer is very necessary in anything that relates with bitcoin and anything that relates with Internet, I don't know how you will coup but I'm talking about myself because I can't stay without a computer because its what I use for making my research.

Instead of selling your computer, make use of it to find a way to make more money. Treat your personal computer as an asset that can bring you additional money for your planned investment. You can easily dispose of your computer by selling it, however, the time will come when your monthly allowance of $100 will not be enough for you and you will probably look for more ways to have an additional income.

Find a way to make money using your computer, there are a lot of possible ways. You just have to find your way. If you have a specific skill you can use to provide service or make a product using your computer, do it for the sake of your investment.

Invest only what you can afford to lose, this is what everyone will tell you when you try to invest into Bitcoin. And I support this no matter what. Investing into Bitcoin is risky but could be fruitful if you can hold it for a longer period of time. That's how Bitcoin investment works. If you were already doing DCA with your $100 investment plan then it's all okay. It may seem a small amount to you but in the long run you can stack it up to make it big.

If you don't need that computer then of course you can sell it to invest in two Bitcoin. But if you are thinking about investing by selling your computer because of the recent market pump, then I will suggest not to do it so quickly. You will find more opportunities in the future. So wait for it. Putting more money does not ensure profit. Holding for a longer period of time ensures profit in Bitcoin investment. So now give you the thought and then decide what you want to do.

You don't mention that Korea, ./ , in any case, hold bitcoin could be very dangerous... sometimes you have to measure many variables in a decision, even as simple as it may seem, at 19 years old you must already be prepared to accept consequences, and I wish all decisions were As simple as that, OP, $600 may not necessarily mean a great decision, it is money that you can recover in the short term, I mention this because of the volatility of bitcoin.

Anyway, you must understand that it is not about selling goods but about having a flow of income that allows you to invest in the long term, in that sense, for example, a laptop can allow you to generate extra income and buy BTC, you can be selling " the goose with golden holes" for believing that you are buying the "golden eggs", is a financial metaphor.

I would say that your decision to invest in Bitcoin is correct but I would not encourage you to sell your computer and then invest that money on Bitcoin. As the price falls, traders make panic sales, which leads to wrong decisions. I also think that being over-enthusiastic about investing in Bitcoin as the price rises can also throw off the situation at times. So you must first accept that investing in Bitcoin is not only profitable. You need to know the main point of Bitcoin investment, now here you see that the Bitcoin price is currently pumping very quickly, and you want to sell your computer and invest here. I will tell you not to be in such a hurry and observe the market for a few days, maybe it can be a bull trap.
Moreover, I will say that the computer is a very necessary device. Having a personal computer is also very important. If you want, you can develop your skills in it as well as invest the $100 for your personal use with DCA management for long term. I see already many people have given their related suggestions so I am not going to elaborate. I just mentioned the matter.
