I'm trying to match some of my other monthly fiat investments into altcoins, at the moment it is not much, but some altcoins (XRP, XLM) seem to be growing faster than anything I can get in fiat growth.
xrp make over two hundred percent increased in price for the past one week so having your investment share in altcoins is good for now. You can also share your investment in a long time coin like creditbit, eth, litecoins with at list 50% of your risk capital and 50% in bitcoin. That is what am doing now.
