Gambling and trading should be considered as a mean of lose and growing bitcoin , they both have risks , but gambling has more risks then trading , the bigger the risk the bigger the wine , there is no fast way to getting rich , if you want bitcoin you have to work for it , learn a skill and offer your services for bitcoin , or join a signature campaign and work you rank up so you grow more bitcoin
Assuming that you actually have experience when it comes to trading, it is incredibly easy to make a lot of money off of it and watching trends. Again, that comes down to experience. if you don't have the experience then it is incredibly more difficult for a decent profit to be made.
A lot of forex experience can translate very well into the cryptocurrency market, so I expect some riskier investors to be using altcoin trading a fair amount.
