I just try to stake my TRX on TronLink and it's done successfully.

I think the problem is your internet connection or your use a low specs device, you can stake TRX as low as 1 TRX. If you problem still not solved yet, you can contact the customer service in official TronLink site [1].

Don't trust Trust wallet, that wallet is suck for Tron because they only support ETH and BSC chain.
