I think the most important thing on the list, is betting all your money on one project, if you bet big on one horse and your horse end up losing that is game over for you, there is nothing like risk free investment in the space and anything can go to Zero
It was a mistake. if someone is investing or trading, try not in 1 project because this can be risky if a large decline. Usually I divide up to 5 Altcoins when my portfolio down with AVG 5 altcoins is not that bad.
but all also return to their personalities. I have been using this strategy for 1 year and it has proven to be able to control losses. especially when there are so many options available
