Probably i would buy 90% of these a bitcoin,while the remaining 10% i will buy ethereum,all of these i will set it for long time holding investment. To lose or gain,i will accept it all,because it is a part of investment.
with 500$ not worth to buy bitcoin. if price bitcoin is 10k$ you only have 0.05 bitcoin. even bitcoin reach 12k$ you only get 100$ profit. not much. invest into altcoin is better in this time
If you want to get greater profits, altcoins are better but bitcoin is way more stable. Altcoins are not that stable. They are open to harsh price fluctuations. I don't feel comfortable with this in altcoins.
