Investing money in bitcoins seems to be an best investment at a moment instead of taking risk and investing in any altcoins or any online sites as the chances of loosing money is higher there but if you hold your bitcoins for long term then it will give you good profits on your investments.
But alt trading is more profitable, than just BTC holding. trade with brain and everything will be nice.
Trading altcoin is good but you need to know what is the best coin you invest to make profit you do research to know what coin jave potential to increase in the future. Holding bitcoin also is good choice because if you see bitcoin price it will contiously increasing and I believe the price will become $3000 more after few months. I dont like investing sute like ponzi, cloudminibg , ponzi because all of this are turn into scam after the founder reach they goal they will run and your bitcoin lose.
