Thanks for kind replies, I think it will be best to hw download my coins using your suggestions. I have no problem to trust a bitcoin company though. It all builds on trust I think. But if other companies does not accept XAPO Wallet then whats the use. you can go with blockchain.info, if you do not like local client for your coins, but i would suggest to use a local client like electrum, armory, or just Core
Yes i also would like to suggest blockchain.info 's online wallet for hot storage if you want to use for instant transaction than that is good choice for online storage, for cold storage electrum and core are most secure wallet.
