BTC, plain and simple.
Don't make a classic newbie mistake thinking that you are too late for Bitcoin, making you focusing on altcoins while in reality Bitcoin outperforms all of them in the long run. I did something similar back in late 2013 when I thought just because I couldn't afford 1 whole Bitcoin that I am too late to the party.
I think it's not too late, but it's also not the right time to invest in bitcoin. The value of bitcoin is quite high right now. As at the end of 2013, the value of bitcoin is quite good to invest. It is important that a good time to invest a certain coin.
What will be the right time? When bitcoin is already at 100k or at 1million? you think btc is high now but it was actually cheaper than its last ath and cheaper than what it can reach in the future but it's also normal for you and for others to have an expression like that. It was not new like what @Rikafip said, it started back in the early days of bitcoin.
Okay, just think of this way, don't think about the whole value of bitcoin but just buy bitcoin in smaller amounts. That is what matter's the most or if you want to, you can just hold you bnb with you because you know, bnb is also a promising investment. It's not bullshit but it has its own utility.
who knows with small capital for BTC.
I have the same thought on bitcoin. instead I couldn't buy bitcoin price in 2013 - well I missed the opportunity. but that doesn't mean I'm late to enter. instead I think that I am currently in 2031 and I regret not buying bitcoins in 2022.
