Trading is the best option for me because all other investements on other sites are either too risky or just ponzi schemes just to scam users.
There is risk involved in trading as well but that will be dependent on your skills.You can try altcoins trading as well as day trading with bitcoins as well.
trading is the best way to grow, but we need good skills. whereas investment does not have to have skills.
the best investment options in my opinion, we can participate in projects altcoin ICOs, it was really good in my opinion to investments there. but you must remain vigilant and see the potential of the coin, because some of them it can sometimes be a scam.
