IOTA is an expensive cryptocurrency asset. Look at its capitalization, at the total cost. I think it is better to buy coins where the capitalization is below $ 100 million.
becarefull buying IOTA at this moment, looks like they have internal problem. i read in twitter in their foundation have conflict and also in their network too.personally i am prefer to buy another coin to decrease the risk, there are alot good coins in market that have cheap price now. we just need to pick some of them. maybe you could look at ontology that have mirroring patter in weekly chart.
