I'm sure when anyone invests for the first time and then gets a big profit, he will be inspired to continue investing and even put all the money there, this is natural and I've experienced when I was a newbie and made me lose a lot of money, after more than a year I realized and understood that risk is a side we have to think about.
That kinda explain why a lot of people has lost their money in alts that they think it supposed to give them huge return. Say for example Luna, after the huge dump people are still willing to put their money into it even with 6.5 Trillion supply and it requires 5x Bitcoin's cap for Luna to reach $1 lol. That's because they have profited from it before.
If you're newbie and looking to make good return, my advice is to be patient and invest to Bitcoin for long term.
Due to lack of knowledge and some mix of common sense or being too unrealistic thats why people do really end up on getting fucked up with their investment because they do really let themselves do make out
action without any basis thats why on the time that the market had opposed on what they had predicted then they would really be starting on whining or regretting on the decisions that they had made out.
PUtting all of your money even with Bitcoin investment doesnt guarantee success although we do see the potential of bitcoin for long term aspects but there's no really assurance.
So invest on the amount which you can afford to lose as always.
