Those who are not doing any analysis are not a trader at all, they most likely a buyer and seller with no trading experience at all. Its ok to be greedy but have that trades using your own strategy and analyze the price trend first, usually traders don’t buy new tokens they wait for the trend to appear before buying. Being greedy is too risky, it can cost you a lot if you do it carelessly, have some time to reflect before buying anything, this is cryptomarket and this market is very risky and too volatile.
Most at times people apply their trading and skills from physical trading and marketing into the Cryptocurrencies space, is that really fair, would that give them any edge in the Crypto space ?
Greed is bad, and one will never make advances if they continue and make greed a top priority. Everyone should have a good limit and stop to trading.
