How much do you make in a month (in percentage)?
What are your strategies, e.g. how do you know an altcoin is worth investing in?

I only make big trades on good cryptos. The random ones are very bad to buy into and out of, because you can't make very much. ETH is a very good one (was at least) when it was cheaper.
