You should invest in icos but not now. In my opinion you can earn biggest amount of money from icos. But if you have 100 150 eth surely you can not invest in best icos . Because you will have not that kind of big allocation. But if you have 1 or 5 eth etc. Icos are the best way for earning money. But surely not now. Wait a little bit. Dont invest in icos in bear market.
