The only difference between owning btc in 2024 than back in 2013 is the huge price difference, the quantity of btc you would have get with $100 in 2024 is far far less than what you would have gotten in 2013.
As for the risk, it is pretty much the same imo, it all depends on the individual involved to be more security conscious, keep the p/keys safe as much as they can, avoid clicking on unknown links, get a hardware wallet for storage.
The question now remains, will hodling btc in 2024 bring any good profit compare to buying it 4 to 5 years back? if your goal is long term, you can always give it a shot. Keep in mind that everyone have right to their opinion and you should not take online opinions as financial advice. Do your own research and invest what you can afford to loss.
