I see that some newcomers to the crypto market have had enough hype that they actually buy alt at current prices thinking that it will never go down or make rich overnight. but in fact it can happen the other way around because the price movement of a coin changes at any time. and people are losing money because they panic after the coin they bought goes down in price.
It is very rare for traders to get rich overnight, because all things need to process through time even in a few days, because not all coins can be hype as we want, so stay away from the concept and desire to get rich overnight because it is a very difficult thing to happen even though it is not impossible to happen.
