vacationgirl Ah. Well, the problem is that Bitcoin specifically has no technological advantage over other cryptocurrencies. The only pros are its market share, ease of trade, exposure through the media (although it's generally portrayed negatively), and a decent community of developers. It also has idealists and criminals backing it. The latter however, are moving away from it due to the increased traceability and transparency of the transactions.
Some 'experts' think the value could steadily rise over time, now that the market has stabilised somewhat. Given that the development team address the scalability problems it is facing (this issue is not specific to bitcoin).
There are many advantages to using cryptocurrencies over fiat. I suggest your husband do his research and
really understand the asset he has bought. Start by reading Satoshi Nakamoto's whitepaper. Then he might be able to make a more informed decision about whether to sell or hold onto them. Unless he already sold them during the crash... in which case, he's already learnt his lesson.
