the more greedy we are when trading, the more higher probability there is that we will lose money. However, there is also much higher probability to make more money. The question is, how much patience do we have and also it comes down sometimes to a bit of luck. Well, look actually isn't involved... But sometimes we get good timing in the market.
This market does not have any luck for investors because everything we are doing here needs knowledge from this market and a small mistake in investment can make you lose a great amount of money. I think that with what is happening, the bear market will probably last for a few more years and this is definitely a big challenge for all investors. I personally hold a lot of big altcoins but I would consider selling if the market cannot improve by the end of this year.
