that's good advice, but I had a newbie ask me about Bitcoin investing. he came with a sizable capital. I give advice that is more or less the same as what you said to invest at the beginning with a small nominal first. but he has other thoughts with bigger capital will also get bigger profits.
he did not consider the greater risk either. he indeed started with a small amount, but he wants to always increase the amount so he makes purchases gradually every time he sees the value of his investment assets decrease.
Many beginners are very careless in financial management to invest, they don't have the patience to buy coins at bear market prices and they are not ready for the risks of investing in crypto so they always buy again when their investment decreases.
So it is very important that every beginner has crypto investment knowledge because it is in vain for them to have a lot of investment funds because they will definitely lose if there is no effect in managing investment funds.
