I'm a firm believer in learning from the past. It's also quite amazing how the world repeats itself much likes it own orbit.
To capitalize and more importantly PROFIT on this fact I look at the exponential growth of cryptocurriencies in the past year or two.
It's fair to say the boat for bitcoin or etherium has probably passed. The market caps on these suckers are getting bigger and bigger with each passing day and that means their scalability (the means to make you rich) are probably very low. HOWEVER there are also plenty of smaller market cap cryptos that have some serious potential and if history tells us anything, we're never too late to capitalize on this emerging asset class where GLOBAL money is pouring in, not bound by any country or territory.
They estimate the global market of gold to be near 6-7 trillion dollars. To date the market cap of all cryptos combined is approximately 600 billion which is still smaller than a single company like Apple. When you look closer bitcoin accounts for more than half the market cap combined. In other words is dominant among its counterparts.
One of my favorite sites is obviously coinmarketcap.com and I use a ton of technical analysis on the information it provides. I suggest you do the same. I expect you will find some value gems hidden in there. Remember if you're trying to make good money from a small investment (always presume you will lose it all) look for those smaller caps with great ideas that are disrupters and add something completely new and more importantly, that can scale! Good luck!
