Ive had some success with a venture capitalist approach. I buy up all the new altcoins that come out for really cheap. most of them dont end up going anywhere but the few that do make enough money to cover my losses plus gain me a couple bitcoins in the wallet. go out there and try new things. only you can decide the best strategy for you
This is a very popular strategy and this is effective if you can avail to take a big risk. Because there are a lot of traders, that mostly do this and take the risk of buying those new alt coins that doesn't even have a guarantee that will be good in the end. But once you started to see a good output and progress on it, everything will be worth it.
