Cloud suggestions: mega.nz and yunpan.360.cn
I use this first site frequently, and I know a lot of other people do, too. I know MultCloud plans to add more cloud services in the future -- I hope Mega will be one of them. As for Yunpan? It's less used than certainly Mega, but it offers friggin' 36TB or more of storage for free, and I hope to see it added as well.
