exactly, it is always better to buy little by little and at low price points and when you are sure that it will rise again. also never invest more that you can afford to lose

If he has 500 000 euros to invest in bitcoins, he could buy some bitcoins and invest some of them in various businesses.

NO need for anything fancy at the moment.

If you want to invest, just buy some coin and sit on it.  You would have upped the value of your investment by like $50 fiat dollars per BTC held doing so:

Eeeeh I wouldn't put much in litecoin. I did buy a couple in 2013, but right now it seems it's no longer the silver to bitcoin. It went almost full downwards in 2014, not accompanying btc's waves.

There are alot of crashes for example the crash from $1000+ to $500 and year or so ago. It is pretty risky to do so.

I have to assume you own a ponzi site because who promotes ponzi sites to someone that wants to invest an imaginary 500,000?

They are not good profit who would pay after he loaded up the site?

Nobody because the owner would do a runner if op actually had 500,000 invested......

500k euro hmm. thats alot amount to invest in networking for me

Haha why networking? 
if I have 500k euros at hand, I would invest in different things and try not to put all of my money into one and only one investment, is it raises my risks of getting burned in the end. And also, invest on things that do not lose value over time and has a high guarantee of profit or even roi. In that way, the 500k euros won't get lost and has a chance to increase. Maybe getting a hundred or so btc isn't a bad investment, given that the prices are low.
