buy some eth or cloud mine for it wich one wins.?
Never pay for cloud mining !
You will earn much more simply by buying bitcoin or any crypto currency if you hold it.
With cloud mining if you are lucky you will recover your ivnersion in a year or more.... or never..

Unfortunately I know it from my own experience...

All the videos on the internet or the comments of the blogs are a lie ...
They do it to promote it and give their affiliate link and they get a benefit.
