kolloh,
thanks for your answer. if I do I will try to buy first small part of bitcoin then.

JRonal12,
is there any big difference between bittrex, poloniex and others trade platforms? I will make today a test account today. still think that Im not ready for trading yet.

Flyyyy,
does that mean that I should be 24/7 online to monitor prices of coins? which android/ PC programms you could recommend for monitoring or alarm notifications?

omonuyak,
thank you. I will start with small steps. ye, it sounds very easy but in practice (me myself too) people are sometimes greedy. but it take time to understand.

prehisto, thank you for your help.

Bitsbytes, thanks. watching him right now. do you know also ryanblue7s blogger? any other good channels to recommend?

dioanna, thanks for website. I was using coingecko before. and thanks for tips how to choose altcoin!

Mindin, thanks. im also interested in mining but in cloud mining. because I dont know how to setup mining farm, then tune it and dont have space for it.

BitcoinPC, thanks for your idea. im still browsing forum. first what comes in mind is mining and buying. are there any other opportunities? i have seen some games and etc... did you mean that? could you please name other ways to earn bitcoin?

big thanks all again!
