Congratulations on your first Bitcoin acquisition! You actually reminded me of my first one too, somewhere between 2013 and 2014. Bitcoin was worth approximately $300-$400 back then, and I had acquired a decent sum of BTC for the money I had paid—it was actually more than I've ever acquired. I'd advise you to create an affordable monthly budget and purchase as much as possible since it's likely to be worth a lot more after the halving, approximately a little more than a year from now. Bitcoin has been an incredible journey so far, and I'm delighted to have been a part of it for the last few years. Don't make the same mistake I did; be persistent and don't give up if you see things going the wrong way.
I agree with your overall point Ultegra134; however, I would clarify that you can be persistent and even assertive with your ongoing investment into bitcoin, but there is no imperative to have to be overly aggressive or to have to try to compete with anyone else in terms of trying to make up for lost time.. in regards to NOT investing earlier.
In other words, I think that it is better to consider the whole ONGOING BTC accumulation matter as a kind of way to be as sufficiently aggressive as reasonable, and to make sure that we do not overdo it within our budgets.. so if we can reasonably accommodate $100 per week, then great, but if our budget does not really allow that much, then we have to figure out what is allowable without overly stressing our own budget in terms of cashflow coming in, expenses and our psychology in regards to NOT having too many extra pressures.
If we keep buying on a regular basis, it is likely that we are going to see progress with the passage of time, but how much progress will likely vary depending on how aggressive that we are able to be without overdoing it..... We should not end up overdoing it, and then find ourselves with few or no coins because we failed/refused to adequately have our budget (and psychology) in a good place to be able to weather the likely inevitable good times and the bad times.. that can sometimes happen in extreme ways both in terms of time and intensities.
Most of the people who posted about this here are Nigerian, and I am not shocked that they are one of the countries using bitcoin. You bought roughly $50 worth of bitcoin, and that's huge. It is really memorable to you, and also what most people suggest is that if you accumulate more bitcoin over time, you should transfer it to a cold wallet to make it safe because, in exchange, you don't own it as you don't have the private key on it. But congratulations on your first purchase, and this is your first step toward owning bitcoin.
I am NOT against the idea of starting out by holding BTC on exchanges or with third parties; however, as we likely own more and more bitcoin with the passage of time, it is likely that we are also going to need to learn more with the passage of time too.
So we should realize that we don't own shit if our bitcoins are on exchanges, but we do own some kind of voucher or a claim to bitcoin and even exposure to BTC price changes, so sometimes it can take a bit of time for the reality of the difference to sink in, and the more we own, the more likely we have to attempt to protect ourselves by investing into studying free or low cost solutions, versus perhaps graduating up to more expensive solutions (such as a hardware wallet), and no matter how are BTC are held, there are going to be tradeoffs in terms of what the risks might be in terms of managing our passwords to accounts or making sure that we have back ups if we start to graduate to self-custody solutions.. that might even be free... but there is no complete freedom in terms of making sure that we spend some time to learn, and the whole matter of holding our coins ourselves becomes easier once we practice more options.. but we also don't want to overdo the complexity of our back-ups or our passwords in such a way that we end up losing access to our coins because we overly complicated our set up or our security.
