I think that is a smart move investing some money won on gambling into Altcoins. This is what I have been doing for a long time now and it has helped me build a nice Altcoin portfolio which has since risen in value over the past 6 to 12 months since I started doing this. Yes it is another type of gambling but the rewards can be huge! and if people invest in the top 10 Altcoins then I think they should do well over the long term.
Well I actually convert my Altcoins into bitcoins so I might not have your kind of experience but it sounds pleasing maybe next time I will try to splash my earnings on some slots as well to see how it goes.
