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.
trading to buy low and sell high not always goes as planned, some people prefer to just holding bitcoin as long as they can. and collect some profit in the future , 3 bitcoin actually is not too huge amount if you consider to do long term investment.
however it is better than nothing isn't it? 100bitcoin will be more than enough for future investment.
At the end is a matter of what you want to do with your bitcoin if you are in to get profits in the short term then you can buy bitcoin and then sell after a few months when the price is higher but you could waste the opportunity to get into really big pumps that will come in the future.
