As i explained many times, If you ask me i would tell you that it is always better you go for trading or investing in coins like Ethereum ,Litecoins etc.Trading is far much better than other options.i would like to mention other options also like Mining which require high capital investment and high amount of care to be taken.Bitcoin doubler is also a another option but that is a scam so it is better to just avoid it. You can try investing your time in Signature and bounty campaigns which are available here in this portal,they really doing well   .
