Answer 1

You haven't included your model code (probably you are using $guarded = [];) but probably instead of
$input = $request->all();
you should use:
$input = $request->except('_method');
This is because additional _method field is added to form to pass HTTP verb method when using Form::model and obviously you don't have _method field in your table
EDIT
In case you have more fields you can include more fields to ignore for example:
$input = $request->except('_method', '_token');
or you can only use get fields you really want to get for example:
$input = $request->only('exchange_id', 'market_id');
(Of course you should add more fields to above - this is only example)

Answer 2

You can use $fillable property of the model to tell ORM which attributes (columns) can be mass assignable. Any other fields passed via update and create methods will be discarded. check at Laravel docs
