mega has "Free bandwidth quota exceeded" problem and it's 50gb space. for 8~10tb asn have to create many accounts. however i think this bandwidth problem can be solve if downloader import links to his account and then download, not sure though.
uptobox is good, they have Happy hour, i think they enable happy hour randomly. also they have 30min to 60min wait time as well.
clicknupload also good.
anyway if we cannot even consider to spend 1EUR/Year for 1fichier premium account, there is nothing to say.
