Trading is a high risk activity which requires a lot of know how and experience to have any chance of success in the field. This makes it the more dangerous for newbies and I don't exclude that to beginners on the forum but in trading as a fied. Your met with those that could be said to have been well experience in the field having had a lot of layers on there skin and they can use this.
Trading isn't for any individual with minimum knowledge, if any individual goes into trading without having the right information they'll lose. Many individuals have lost millions in the market because of this. Trading is more riskier than investing. Trading demand to be more active in the crypto market because as a trader you depend on news happening in the market to determine if you'll be putting in a buy order or opting out of the market.
Investing requires minimum work and attention. Investing has less risk involved as if you have patience you can always profits from investing in Bitcoin. Investing in altcoins on the other hand has the same risk as trading so unless you're ready to lose it don't do that.
