I suggestion you first do your homework and research on what you want to buy. Decide the size of your account (money you will not miss) start with a small number of cryptocurrencies.  For example four and monitor those for a while until you get the hang of how thing work with your wallets and your wallet addresses. Learn how to protect your wallets and use strong password on your accounts. Remember the markets is still young and very volatility. The cryptocurrency markets will be here for the long haul. Three elements in the development of the cryptocurrency market;

Innovation - The purpose in which something is done or created or for which something exist. Know the purpose and why it was created and why you should support the cryptocurrency market. By supporting the cryptocurrency you are putting a human face to the creation. Many people in other country do  not have the freedom to decide where and how their money is manage. Know the different between a centralized and decentralized economy.

Acceptance- we are on the pier of acceptance. There a struggle to get fully accepted as form of currency,and the market displays this behavior in the market reaction. So you going to have your negative and your positive news, feedback and advice from the experts. (follow what you think is best for your developing your leadership) Row your own boat. Focus on what work best for your bottom line and don't try to play hero right out of the gate. Develop short term and long term goals for you portfolio. Your portfolio will change overtime and that ok make the adjustment and move forward, if there a win or loss.  Every day their a winner in the cryptocurrency market it is a delicate dance. Learn the Tango, lead with the waltz and know when to hold'em. Most important keep up to date on the market read a book on cryptocurrency, cryptocurrency mathematical analyze. Yes it heavy. You are playing with the big boys and you need to know how to navigate the waters.

Saturations is not here yet. So I cannot make any predictions on where the cryptocurrency world lead us.

It a very good time to buy, stack and hold.

Don't waste your time investing in gambling site. The odd are always stack against you. It will benefit you better if you dig deep and learn more about the cryptocurrency market and where it is leading you in the future. Better yet tutor someone on how to's  in the market and share the wealth of knowledge.

If you are thinking of downloading your wallet to a cold wallet aka hardware wallet. I suggestion you reformat your drive and create at least two copies. For example a USB with nothing on it and of good quality. Keep in a safe place and check it often to see if it up to par. Never use a desktop wallet.

The Bitcoin are very young at this point in time. It will be very unstable until a solid foundation is established.  Like any business are profession you must grow with your goals in mind. If you first brought BTC, their a reason you did. Trust your first judgment. Do your homework and research before you decide it is not for you. Keep those coins you decide to not  to trade (in what I call) on a quiet  watchlist they can come back alive at a bottom prices and become masters of the game. Rule keep 2 percent in BTC and buy ETH with the rest.  Good Luck
