Introduction
Crypto prices has risen significantly in the past 2 months so I decided to do a follow up post. This is based on a previous post of mine titled Bitcoin return on investment : 2 years. I suggest you read that one first to get a better understanding of what is to come but it is not required. This time I would like to look at how an investment would have performed for several cryptocurrencies. As you can tell be the title, we are gonna look at a 2 year period again.........Well technically the period is for 25 months. The data ranges from 19 December 2018 to 20 December 2020.
Disclaimer
I am not a financial advisor and this is not financial advice. I take no responsibility how you interpret the below information.
Invest twenty dollars (USD) a month in 7 different coins
We will also implement the same methodology of "stacking sats"(although that term is only applicable for bitcoin).
Also USD20 (+- NAD290 depending when you look) will still be used for a monthly investment
The analysis
I retrieved the data from coingeko.
We will still go with the four scenarios, which were the monthly minimum; monthly mean; monthly median; and the monthly maximum.
The coins
I chose 7 coins. Bitcoin(btc), ethereum(eth), ripple(xrp), tron(trx), dogecoin(doge), monero(xmr) and cardano(ada). Some of them I am holding, others I have sold after I got more education. I tried running a full node for monero once but it only managed to download about 70% of the blockchain....so I gave up. Quitter!!
Like in the disclaimer, this is NOT financial advice. Some coins people for hold long term, other coins are used for speculative purposes. My main aim is to provide the analytics, NOT to recommend which coins to invest in.
The results
Below are the charts and price summaries for the seven cryptocurrencies.

Conclusion

The coin showing the lowest median ROI is tron with 59%. If you think 59% is low, try finding out how much interest your bank is willing to pay you for a fixed deposit or other investment vehicle. The best performer is ethereum(226%) with bitcoin(219%) at the number 2 spot. Like I said earlier, this is NOT financial advice. I am merely providing you with the analytics.
Hope you liked it. Feel free to let me know if you would like me to do something similar to a coin of your choice. See you next time.
