I think that saving is the better cause investments is always risky, you will never know what you can got at the end, so better to use safe ways.
but if you save in bitcoin it is also possible that you will never know what you can get at the end. LOL.. it is possible that after a month or few month you check bitcoin price and you see bitcoin price dropped like hill..
Investment itself is not a bad thing . but investing in scam, ponzi and fraud sites is bad thing..
we need to determine those scammers and keep ourselves and others away from them. and encourage legit investment sites to come front.
In the first place ponzis and HYIP are not even considered as investment because it is merely a game that the operators win all the time. If you are planning to invest, just simply hold your bitcoins but do not failed to do your duty to monitor the market so you can sell and buy at the right timing.
