Incorrect validation message when claim amount is too low, and number of decimals > required

[elena-zh]

Select investment option USDC to claim
Enter too low amount 0.000000001 (with 9 decimals)
For ETH/GNO option enter an amount with 19 decimals (0.0000000000000000001)

AR: 'Your investment amount can't be zero' validation message

ER: I'd expect 'Enter a valid amount' or so as the validation message for this case

well, true, we could limit for the precision of the token, although i think is super low prio.

The case affects just the warning message of users who try to add 19 decimals for ether and 7 decimals for USDC. And not even that, we allow it as long as its over one wei in the unit.

Closing cause its not worth the effort imo. Re-open if you think is imp
