I think that mining altcoin is attractive for small miners. The complexity of mining altcoins is lower than the complexity of mining Bitcoin. Therefore, I think that small miners will actively mine altcoins.
Even the altcoins which are outside the top-100 list in coinmarketcap have on average 10,000 or 20,000 users mining at a time. The rewards can get pretty low, in case you are going for CPU mining. And I would say that it is definitely not worth the risk of getting your AWS account banned. OP is having $200 in his account, and it may be better for him to use that balance effectively.
It's not a recommended way from the beginning to do that actually, cloud service was not putting GPU as its main resources but use good CPU and this time CPU is not even profitable;e even you mine with a lot of it because most of algos will be efficient for GPU.
This just a way to waste our time to get zero value.
