I am investing and hodling cryptocurrency since the beginning of 2017.
I am building up my portfolio based on the Coin Market Cap with a few small diferences based on my own preferences.

I first bought BTC, ETH and LTC. Lateron i started to diversify my portfolio with mainly top 30 cryptocurrency.
Lateron i added Stellar lumens, Ripple and Bitcoin Cash and Waves.

I but every month a few new coins and add it to my holdlings. My strategy is to buy the dip. So when prices go parabolic i dont buy.
But in 2018 when the priceses were low i added some privacy coins to my portfolio.
I bought Dash, Zcash, Monero all 1 of them each.
I also added some penny crypto to my portfolio. My favorite is Doge, this coin has a much bigger share in my portfolio then it has in the market cap.
Also i have Verge, Digibytes, and Redcoins.
As last I bought tron, cardano and binance coin as the new coins of which i expect they will do good in the future.
Agi is my only ICO out of 4 which kept its value. 2 went 2 0 and 1 went to 25%.
As last I earned Niko from and Airdrop and BAT from coinbase Earn.

For the rest my portfolio is made up of Airdrops and coins i earned for free.
The advantage of coin market cap based hodling is that BTC is 50% and that the loss was less in 2018 then when i invested in altcoins more then BTC.
After last weeks surge i have profit again. So i paysout to hodl based on the Coin market cap.
