For the 3% gambling guys here putting all their money into bitcoin might seem to be good idea but i prefer to invest in less risky manner. Bitcoin market isn't the most stable, all know that. And finally we have pay our bills with other currencies still

I'll invest larger amount in bitcoin if i have larger income. Thats the strategy for now

Even if you have higher income its always good to put only certain percentage of your income in bitcoins as you never know what will happen to bitcoin in future and if price falls then it will give you big loss.
Completely agree with you. There must be calculated risk because of the nature of btc.
sometimes bitcoin geeks will not going to think about that,they're putting their wealth on bitcoin for pleasure,and it's seems like a gambling indeed but if they like it then we can't do anything,only spent what you can afford and thinking twice before doing for a wise decision
They can do that as they are willing to invest on there skills, by investing in themselves they can trade bitcoin which will give them consistent income and they can even make that in a daily basis. That's why day traders are here and they are getting richer because of their passion.
If you want to make good profits from trading then you need to invest higher capital as you can make descent profits even with a small fluctuations and if you have invested in altcoins then profit margin will be even higher in compare to bitcoin trading as altcoin market involves huge pumps and dumps which is not possible with bitcoins.
