You can not count on crypto as a source of permanent and stable income. This applies to any sphere in crypto: airdrop, bounty, trade, exchanges. In either of these items, you may fail or have to wait too long for a well deserved reward. Some coins received as reward for the performance of tasks, may not soon appear on the exchange or do not appear at all.
To be honest crypto currency is helping me out now though the earnings that Im getting is not that high yet. And I really believed it would continuously help me a lot with regards with my financial aspects in the future.
