Bitcoin has raised in USD terms from 2 to 30 and it will be here for long time, it isn't going anywhere you would be able to buy it 2 years from now but silver on the other hand might disappear from the market in 2 years .
Bitcoin in its early stage of innovation right now and not even near adoption point.
Silver on the other hand is near panic buying phase .
Put your manic price predictions aside and think clearly for a second you can buy something which was money for thousands of years
or something that will be a form of money 5 years from now which is currently in its early stage of innovation, and if even BTC/USD price go to 90-100 area don't you think it will be at the same time silver go to 500 .
The only reason why silver trading at 29 and bitcoin at 30 is because central banks worry more about manipulating silver price and not BTC price.
Use your leverage and buy silver if you didn't done it yet.
