I disagree about saying investing is minimal risk whereas trading is a lot of risk. It's about sizing and asset allocation.

If you invest a large percentage of your portfolio into one coin, that can be a large risk as your downside can be great if its price falls.

If you're trading, and you size your trades appropriately, you choose your position size such that your risk is a set percentage, for example 1% or 2%. If you trade then you should be using stop-losses, to set that particular percentage.

Also, you have to determine when a "hodl" investment is a good "hodl" or one of those cases of "letting your losers run", otherwise there's a contradiction there. In saying that, not all "hodl" investments are good ones.

Another point is opportunity cost is often forgotten with risk. You risk opportunity cost if you invest in a coin that takes a relatively long time to rise in price. Long term profits are always more obvious in hindsight.
