Indeed you have made a good choice this year because, the price of BTC is still low to a level were you can buy as much you want and hold for a better future. I will advise you to hold for like 6 months before you can sell because, it will really help you to enjoy a big reward from your business and it will also encourage you to save more money to buy more BTC in future.

Don't forget to store your coin's in cold wallet always so that you will not experience anything that will hurt you in future.

Addition advise why you should avoid centralized exchanges.

1. They can get hacked from any attacking source
2. There's no privacy in using them because they can leak your data to third party
3. You cannot recover your asset with them whenever there's something wrong with the exchanges either being attacked or went bankrupt because your keys for decoding your wallet address on blockchain is with them
4. You're prone to KYC and AML agencies to investigate your informations abd account being subjected to them.
5. You're no difference from someone using a bank because everything you do under a centralized exchange is from a central authority like the banks and other centralized institutionizations did.

Banks are better because they are likely to protect your fiat than exchanges will protect your coins. There can be robbery in your bank, you can go to another branch the next day to deposit or withdraw, you can make use of their online banking, this is the way banks operate in my country, but if an exchange is hacked, your coins are gone or inconveniences may occur.

Don't use exchanges as your wallets. They provide you custodial wallets and they own keys, not you. After all fiascos from Terra, Voyager, Celcius to FTX exchange, please stop automatic believe in exchanges to hold your coins.

Reminder: do not keep your money in online accounts

Anyway, I wish you all the best for making your dream come true today. Moreover, another important thing is that you are able to invest in Bitcoin as a student, on the one hand you understand the importance of Bitcoin and how its popularity will be in the future. It is very significant that you have invested Bitcoin in addition to your studies, your inspiring work will make students interested in Bitcoin. But my personal advice for you is that you focus on education first and then focus on Bitcoin as time permits.

Not to mention if they close your account for whatever reason, your money is usually gone to you. They don't have to go bankrupt in that case.

As your balance gets larger, you definitely do not want to write about it online, because that will paint a target on you for hackers, and scammers will try to send you fake messages and phishing links as well.

I know hardware wallet devices have to be bought with money, but they aren't too expensive. Though Op says his BTC is $163, so i don't think he should buy a hardware wallet yet for that amount, but it doesn't mean they have to store it in a hot wallet, OP is a newbie who might not know how to correctly use their online phone with BTC in it, they could click on one link and their BTC could be gone.

I believe once a person buys BTC, the next important step is securely storing it, if OP has a device that they aren't using anymore, they can format it and use electrum on it as a cold storage. $163 is dust to a lot of members here, but if that is all OP has and he wants to hold it for long and accumulate more to it, then they have to protect the money.

I wonder how much time it took for you to collect that amount. If I had invested this amount back when I was in college then I would have got great profits by now.
It's good that you are trying your best to get started with bitcoin but I will recommend you to start learning more about bitcoin and trading.
Learning to trade will help you to avoid making mistakes that can lead you to potential losses.
Start learning more about finance and management so that you can increase your portfolio over the years.

Kudos to you for your efforts and wish you all the best for your dreams to come true.  But I have some doubts that this story of yours is true.  because there are many users make such story most of which are being done for the purpose of getting merit.  Meanwhile you opened the topic today and you are saying that you are the first time to invest in bitcoins but on January 10th you made a post that you are investing on altcoins.  And there you said you don't have much patience to hold bitcoins for long term. here you say you save your tiffin money and collect bitcoins.  The word is not two kinds?

on the other hand you create this account and participate on quiz with your first post for getting merit and you successfully got 1 merit there.
So it's not suspicious that you have another alt account. and this is too is a neat story to get merit
