Also not the captcha thingy faucet which needs thousands of clicks for just 0.0000XX btc per harvest?
Thank you
100% of the investment websites you see in the market are all ponzi. They will promise an unrealistic return on your investment. Once you invest anything with them, you will probably receive payment for initial few days. But after few days, they will certainly run away with a major chunk of your investment. I didn't find any website which actually takes care of your investment.
Instead start hoarding up your bitcoin in a safe wallet for the future. Holding is also an investment for the bitcoin. Have a long term goal and save maximum amount of bitcoins you can. Don't put everything in a single wallet. Instead use more than 3-4 wallet and keep your bitcoins there. THis is the only risk-free investment of bitcoin that I know till date.
