Hi I will invest to any idea about earn bitcoin. I would start from 0.1 BTC. If everything will be ok I pay more more money

You choose the right way. Because I think now a days investing is the best way to increase btc.I appreciate you that you don't choose gambling because that's very dangerous and can make you empty hand.So, do trading but be aware of scammer.
As what people are saying that gambling is not good for them base on their experience as they have lose a big amount of money. Investing in bitcoin is really good because we have a good future like majority of us believe. However, since we cannot see the future, we should not limit our investment on long term investment only.
