I think do both. So one day you don't lament and will get twofold advantage from both. Since exchanging can make open doors for you to win pay. So is the abundance battle. So you should attempt to do both and buckle down with abundance.
Yes both. You can do both at the same time. While joining bounty campaigns, you can also trade and it complements the other also. Day trading, short term trading is also good as long as you are very active online and being updated always of prices.
