I'm quite new to cryptoworld and this trading thing seems interesting but before jumping in to that, I'd like to know what kind of profits can you expect? For me, trading bitcoin to altcoins would be possible, or possibly bitcoin to fiat. What kind or profits have you generated in percents, please. For a month (or week, or year?)

I came back to London after being away for a while and noticed something is different. Now there is all kinds of bitcoin (and ethereum) commersials all over the place, trying to sell people crypto investment services. I've always been told that if investing becomes so popular that it is discussed in the pubs you should sell. This makes me kind of worried. What do you think?
