It is good time for investment as in a day itself it has jumped 600$+ and if had done investment yesterday also would have easily made money of 600$ per btc . So before it rises further buy now and keep investing in good altcoins or in btc .
For me investing in real estate is very profitable in my country but it will need a huge amount of money compare on investing in bitcoin, it's not required a very huge money but we can still earn a lot of profit if we can keep our bitcoin for long time.
