Still too early to tell, OP.
Though Bitcoin shows its convenience already with what you mentioned, without the use of ID verification, there are still many things to consider with it.
Even though there isn't KYC verification, we still have mining fees that some have problems at.
Speed of transaction is quite an issue to some as well unlike fiat that personal transaction done is == to transaction instantly done and concluded.

Two things.
1. Why would a celebrity do such giveaway like this? And if it is a giveaway, why need to send or even deposit BTC? That single word of sending something is surely a scam. That's why I don't trust these giveaways of any forms anyway.
2. Elon Musk, really? This is why I don't let myself being celebrity driven hodler. No matter what celebrities claims at to crypto news, I don't usually take their word in its face value.

Ah yes, that incident.
Good thing I don't follow those celebrities, well not that I would be affected anyway if I even see them making those crypto-related posts.

I don't have any thoughts about the dude's sentence, but instead I realize that everyone can be a victim in social media of these types of schemes regardless if one is a celebrity or just a typical/ordinary person next door.
It even shows that even these accounts of a large platform can be social engineered.
I am even more concerned when it comes to Facebook because there are a lot of scams popping up in random comment sections.

Yes. Those newbies that tend to still search out those coins that are way too below the rankings and still expect something out of them in a day.
That I would advise not to.
What's worse is that these newbies don't even think of going back to the market now after the long losses that they incur in the market.
They either get too emotional or just think that trading doesn't really just work for them.

Not sure if they're too many, because those tokens would even reflect on how does an exchange perform sometimes.
One notable example would be BNB. I plan to buy it back in the days, but it was just too much in my portfolio now so I backed out.
It seemed to perform well along with the exchange based on the circulation and the volume of the coin.
That's just one notable example though.

#4 would be affected by the other factors you mentioned in the list.
It would be in demand if there's such plentiful use to it, OP.
Sadly many coins just tend to be for quick $$$, but it ain't for longer term and in the end it is still okay as there would be still top coins to be hodled at.

Your friend is just one of those people, but still you never know what others think in investing in BTC right now.
Don't they want that moon dream in price? I wouldn't convince your friend if I were you. Just continue buying and let others be left out and regret their decision into not investing one in here.
It is not too late for someone, OP.

Not too late for you fella to still invest in Bitcoin.
You could diverse into both coins.
The usual 50/50 diversion, unless you're kinda choosing more coins below those top 2 coins in the market right now which I don't do just yet these days.

I hope you find your choice already from the top coins from the answers we provided.
It's kinda risky now to stray too far in the coins popping up in the market.

We buy bitcoin not because of only hodling for it to earn money.
Some have different reasons, one falls for using it to pay, another is for storing for its value and the last is both of two sides.
I do the both sides of the coin, but when I get asked when I will sell my coin. I always say anytime soon, but I won't go all-out in my coins.

I'm not that into songs that much especially when it comes to technologies. I take it to its level where I only go with the technological part.
The song is pretty much just flat, nothing felt like it would hype me into the song.
It could be a chill song, but not something to hype me up. Still a good song though, not gonna lie.

Not sure how long as Bitcoin is still stabilizing above 57k as of writing this.
I would just advise to keep the profits in a stable coin so that you'll be able to keep your profits and just keep the capital that you'll keep hodling.
Not every alts are worth hodling in these times.

From how I traded back in my days, it seems to lean at that part already, OP.
I don't see plenty of merchants accepting Ethereum for their businesses, but instead it gets used as a smart contract for some.
Many are now mentioning about the whopping price of the gas fee lately and I believe that's not favorable for the utilization of it for a casual transaction.

Through virtual trading, yes it is possible.
But here where market doesn't sleep, nah. Basing your actions from the history of the past won't help you that much aside from the pattern and prediction that could possibly lead to your speculation.
Remember it's unstable market after all.

This might be a non-crypto related but I quite remember that there's like a creepy app in the Google Play store that would even scare a child because of its "killer voice" tone and it is disguised as a cute character of course to avoid detection.
If those types of apps even managed to get past of the policies of the App Store, who knows what more if it is in crypto space?

Problem is these apps will still exist and will only be removed if one managed to report it. Imagine how many people already downloaded the said app before a report comes up.

This is why I don't really rely too much on mobile apps when it comes to cryptocurrency or anything that involves my money or coins, as well as that I don't download MyEtherWallet even if the site wants me to.
There's lacking of Quality Checks on these apps and  you never know just by the app description of it or even the ratings, because fake reviews are quite common. Just install the app and you have the means of rating it now.

At these times, I would just go for Ethereum and Bitcoin in the non altcoin side.
I am not currently holding Ethereum yet because I put them all into Bitcoin, but yeah there's still no reason for me to invest in below top 10 coins in the market.

Lol. It's all about the money anyway on why they're willing to shill any coin.
I don't believe in such crypto influencers, especially when they're targeting Bitcoin.
It goes against the decentralization that Bitcoin has.

Whenever there's someone randomly asking you to send money to an address regardless of who they claim to be, it is surely a scam.
These types of phishing/scams you mentioned are quite common now.

I had my experience before in the altcoin side, which I don't even expect that I would get anything because it is surely just a waste of time, but they went really far. The scam email I received even wanted me to go to their site to put me into their phishing MEW site.

Dang. I thought you'll forget about the thread you made back in December.
We're having a lot of nostalgic post lately here in BTC Discussion, huh?
One user even recalls another post that was still back in 2011 when someone asked if one would buy BTC if it went below $10.00
About the 80k mark? Sure, but we still have a little way to go. We're getting a lot of price corrections lately.
