those are words of good advice.....most of the time. Even Warren has said that he himself has made some bad investment decisions, that he has been lucky in most of them to get out before he lost too much. You have to know that not all negative sentiment is worthy of investing in.... i can give you a case in which a lot of financial investors put large investment in and lost their butts on.... Xybernaut(XYBR) , this was a company that had made one of the first wearable tablets for industry.... their stock was somewhere around $4 a share when it announced it's new product set to revolutionize the field in wearable computing. almost overnight their stock went to about $12 a share.. then Both Amazon, and Apple announced they too were developing a portable tablet in PC format... XYBR's stock dropped right back to around $4 a share like literally overnight...in part because of the Amazon,Apple announcements, and also because the CEO was being investigated for mishandling of the company's money.. the stock was delisted shortly after renaming a new CEO a few weeks later.... Afterall, investing is nothing more than speculation. There are just safer investments which tend to be consistent with a payoff, and there are those investments which are high risk, and may never payoff...but when they do they usually payoff big to those who were in it from the start.. That is kinda how i feel about crypto's .... they are currently a relative high risk/reward investment...currently the only crypto currency that has a relatively stable value is BitCoin.. everything else fluctuates wildly, and cannot be traded with any confidence that you are going to make anything on the trade... That's not saying you CAN'T make money on them, just that the risk is definitely higher than say, trading the Yuan...or AUD...
