You can still trade with that number. If you have less trading experience or this is your first time, please prefer long-term trading as bitcoin is your choice of coin. You can still buy some $50 worth of btc today while it was at a low price and then wait to pump for a while. You can re-buywith these when you have income. And, be a bitmex swing trader or do some margin trading. FYI that it was kind of complicated than the normal btc trading so you've got to make an effort to expand your knowledge of it before moving into that kind of trading.
