I think an investor should invest by looking at the reality. I have to take decision considering my financial situation. Being a normal investor I should never be interested in getting too much.
Well thought of, for you to invest according to your budget. Whoever calls him or herself a crypto investor should learn not to invest above their weekly or monthly limits in the pursuit of financial profits in crypto. That's not all; they should invest with their spare money and also have a moderate selling price in mind for them to sell their Bitcoin or altcoin.
Both of you are right, but on the other hand, I believe it is still not bad if an investor finds a really good opportunity and tries to push himself a little further to invest much more than his financial budget can carry, because we all know that in this space and type of investment, the higher you commit to good opportunities, the higher the return in the form of profit whenever the price of that asset rises.
I myself have made lots of investment whereby by the end of the day, I wished I had invested much more, even if it meant me borrowing money from some reliable sources.
One thing we all ought to know is that, in the journey to success, one must take risks, one mustnt dwell in his comfort zone all the time, because most of the time, what will take one out of trenches is usually not in his comfort zone.
I would say, invest wisely, but push yourself when you find a good opportunity.
