I have 0.50 ethers and want to invest half in BTA ICO (if that begins) as I am waiting since last year but don't know if they have a plan to launch it. Therefor I don't know if they launch or not or maybe sooner so I don't want to spend those ethers but need your advice regarding where to spend half of other ethers? Please only suggest me some good ICOs just like Maker token for long term (an year)
I don't know what your overall tolerance for risk is, but if you only have a small amount of ETH to buy tokens and are scared of losing it all, then seriously consider to buy into a basket of cryptos (such as CombiCoin managed by Triaconta). If not and you're ready to outright gamble, you want to make sure that you get into the best ICO possible (or a post ico token that is undervalued). This involves a lot of reading and research - and probably the most important part - doing your own due diligence.
P.S. Don't see the above as investment advice. I am just sharing my point of view based on my personal experience in this space. You should consult with a professional to determine what may be best for your individual needs.
