In every trading you should have a capital but we could trading without involvement of money but with efforts we contributed in bounty campaigns cause bounty can give us tokens that you can trade in other altcoins by participating in their program they pay tokens after endorsing their project.
Absolutely right!!! We need capital before doing trading you can try to lend in some trusted member in this site or you can try joining in bounty campaign all you need is time and effort when bounty finish you can earn some money then the money you earn can be use to start trading so good hoping you can get some profit soon, trade wisely.
