Have you heard about airdrops? Because of airdrops i traded without capital before. Airdrops are token given by a newly project that is about to start. They will give you tokens after doing tasks like following twitter and telegram. Then if you do the needed tasks you are able to get tokens that soon you can trade if they are on an exchanger already.
but most of the time airdrops gives you a small capital to do trading or sometimes it has no value. the best thing to do is to join different bounty programs that for sure will be beneficial to do trading because of huge amount to earn.
although we get small capital from aidropm but if we accumulate it for a while it can be big amount.we just need to be patience working in bounty and airdrop.it can not give us much money instantly
