Dear users,
I want to recommend you https://btcpop.co as a very nice site to grow your Bitcoins and altcoins.
The site offers many different things:
Loans
P2P loans. They are reputation based. Borrowers build a rating.
Loans can be insured. That means, if the borrower defaults, you can pay back the insured part of your loan amount.
There is also the feature to put collateral.
One can put altcoins and shares as collateral and the loan into risk free loans.
ICOs
You can put your investment project on the page and collect money for that. After that you can pay your investors dividends.
Altcoins and shares exchange
After a successful ICO these projects become shares which you can trade on the shares exchange.
There are also many altcoins you can trade at the exchange (ETH, BCH, LTC, XMR, DOGE and many more).
The altcoins can be used as collateral.
The altcoin exchange also offers nice arbitrage oppurtunities since the exchange has no API, yet. By manually checking the prices with other altcoin exchanges you can get a nice arbitrage oppurtunity.
Staking
BTCPop has a very nice pool for proof of stake coins.
At the moment the CLAMs staking pool is very profitable for example.
You should definitely take a lot at this site.
