I saved around the 3 bitcoins and I think that it can still be very profitable with enough patience.
Good thing that you have saved around 3 bitcoin because I haven't save too much. Just don't let yourself panic upon seeing the price to fall down. And perfect example is what is happening today, the price is falling very fast but still just keep on holding those coins. Because it will do a comeback just like what happened from the past.
If he is a trader then he could have sold when the price was above one thousand and then buy again when the price got lower if he did that he may have something close to 4 BTC instead of 3 BTC.
