Sure people should try not to be stupid, since no one should want to lose any money, even if it is ONLY $10.. yet if they start with a small amount, then their security should be in line with the amount invested, and realizing that if they hold coin with a third party then there are various kinds of risk but also that if the bitcoin gets stolen (like through a hacked account), then it is likely that the transaction is irreversible if the hacker takes the bitcoin, even if the bitcoin is with a third party..  At the same time, holding private wallets can also be complicated, including if the bitcoin are held on a hot wallet versus a cold wallet.

These matters of the various kinds of wallets need not be learned prior to getting started, since getting started is one of the most important things. and yeah, there is a difference between the incomes of people in regards to how much security that they might feel that they need based on their income and/or their other resources, so there is a difference between investing $10, versus $100, versus $10k versus $500k or some other amounts...and yeah, sometimes there needs to be extra security to account for potential changes in value.. since for example, even in 2020/2021, there might have been some guys who might have been somewhat lax in their security if they had $8k invested or in a wallet, but then after the BTC price went from $7k to more than $60k their $8k might have all of a sudden turned into $70k-ish.. and similarly in 2017 (although that is further back in history, when $5k to $8k might have been in some wallets and the BTC price was around $250-ish in mid to late 2015 - yet by late 2017, the BTC price went up nearly 78x, so that $5k to $8k would have turned into $390k to $624k, and so that would have been an even more extreme example how the security should have been more important, since maybe a person might have been o.k. to keep $5k to $8k on their phone.. even though that seemed a bit much, but then if the amount turned into $390k to $624k.. then they might have become quite nervous since maybe their whole networth might have been less than $50k and then all of a sudden their whole networth goes up 8x to 10x or more and much of their value is on their phone, which would not have had been a very good and/or secure place to be. .even though I think some folks did find themselves in those kinds of situations in 2017.. and their security did not keep up with the size/value appreciation of their BTC holdings.
