What's wrong here? As long as you are investing money that you can afford to lose, the there is nothing wrong with buying. Keep buying! You won't regret on the long run. Just don't sell when the market is crashing. You will be making some decent profit after few years. But if you are risking your money (by risking, i mean you are investing money that you can't afford to lose), then just stop and hold whatever you have invested. Don't invest anymore. Forget about your coins and come back after a decade or so.
yes i always refer and suggest this type of investment that is to invest those money which is spare because it will be a big injustice if someone invest the money that is for their daily life because nobody knows about the luck and the bad and good timings although exceptional people are there but one should not risk that much to invest whole of their money including the money for their basic needs.
