my view:
there is no trial version. you buy the license(s) for one (or more) exchange(s) you plan to use for your trades. then you send your API key from the chosen exchange to the author of the gunbot to get activated. download, configure and let it do its thing, possibly never turn it off. you run it 24/7/365. bot will start trading. if you buy a new license it will generally set you back 0.1 BTC, but you can buy a second hand license cheaper here on the forum (just make sure via gunthar that it is a legit license). use the rest of you money for trades (more than enough for a start, perhaps disable "double up"). I have run it with more than 10 times less than you have. It does not matter, you can set the trade value in BTC as low as your exchange will allow. I ran it with 0,003 BTC per trade on Kraken, it ran just fine on five pairs with 0,015 BTC capital on disabled double up. Running it with smaller value trades is advisable in the beginning as you learn the bot's responses to market swings and as you tweak the strategies to suit your trading style. When you get consistent results you are happy with, you can set trade values higher and maybe inject some more capital in your trade account.
