I can tell if something is silver very easily. Magnet test and sound test.

If you're holding Crypto during this bear market might as well make compounded interest on your holdings. I traded my stellar I got for free from blockchain wallet from that recent airdrop and sent it to the Bitcoin Faucet. About 6 months ago was able to deposit $500 of bitcoin about .05 and now I have worked my way to a total just over 2 bitcoin by stacking compounded interest in satoshis and randomly spinning for free satoshis. My goal is to have 5 or more bitcoin by the end of 2019. If you have crypto just sitting there might as well gain interest and see where you are by the time the next bull run hits. My gut feeling is the bullrun will not happen until the end of 2019. The next minted millionaires are the people who are solidifying their position in bitcoin at this very moment. Stack some satoshis.
