Start with whatever you can afford, decide on an investment strategy and stick with it. Don't let emotions cloud your judgement.

My strategy is to use GDAX, the trading platform, to buy ETH for example, and then trade in bite size pieces. Take small profits on several trades and keep reinvesting. This way, you can make a profit regardless of where the market is sitting. At the same time you are making small profitable trades, keep some long trades, then when the market spikes, you'll win on them too. Cash out for a nice profit and then reinvest when the market is low again.

If you don't have capital to get started, you can scrap togther bits of crypto from faucets and mining games. Follow the same procedure as I mentioned and you'll still profit. As you make larger profits, keep reinvesting. I put together a free report on my website that outlines my faucet project, if you're interested in investing your time to claim some crypto. The report is at http://terrytelford.com/free-bitcoin

This may not make you the richest man in your country, but it can give you a headstart

If you are willing to invest quite a bit of time, you can use faucets to generate ETH and Bitcoin too. If you visit my faucet page at http://terrytelford.com/best-faucet-accounts you can join some faucets that will start generating some ETH for you. ETH Combo, the second one on the list is specifically focused on ETH. It takes time to collect, but it doesn't cost you any money.

If you're bored, you're doing it right Investing is not intended to be an emotionally driven activity full of excitement. If you decide on an investment strategy and follow it, it should be a bit boring. Although, I have to admit when your investment doubles or triples or more in a short period of time, it is difficult to stay grounded. A little dance is sometimes inevitable 

I suggest buying as much as you can afford now. Buy ETH or any crypto and then ride the coming wave. Sell when the prices are high and then repeat the process. The market is predictably fun

The way out is in your mind. Establish your investing strategy so you have a basic road map for how you are going to manage your portfolio. While the market is low, like it is now, buy as much crypto as you can. If you get rid of the "chicken little" mindset, you'll have a lot less stress. The sky is not falling, the market simply moves as it always has and always will. Sometimes it's high, sometimes low. The easiest strategy to follow is buy low - sell high and don't let your emotions get in the way

Nice list and predictions. What coins do you own?

Hold on to your hat, this year will see some very exciting increases for ETH
