$1000 for a common user is not a simple thing, it is a big amount for a common man in a third world country. Regular spending as investment for a longer time period needs to give long term promised profit. For this bitcoin, ethereum and top listed altcoins were the best pick. In between one can prefer investing into ico's that has got good future to get good returns in short term.
$1k weekly isnt really simple and besides this is already a 2 month salary here on my country.So, basically this is really an opportunity for OP since not all do have
the capability to save up this big amount on weekly basis.When talking about investment then buying out BTC or ETH would be the best option if you are not into trading.
