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)
Why are you hasty for looking for an ICO to invest? You can just hold that ETH you got. Wait for ETH to pump again up to $1,200 and then decide to invest into such ICO's. I wouldn't advice you to invest to ICO's for now as the market is still on recovery from one the biggest correction we've been through. But if you are really hasty and you are looking for a good ICO to invest go at your own risk.
Since the market is on a down way, I think it is better to buy some cheap major coins like ETH and eos, I think it will recover soon and this coins will pump a lot firstly.
I would follow this advice OP if I were you.
