I think Bitcoin is the best investment for long-term investment and ethereum for short-term investments. Now you decide what you do. I hope Secure investment in investment at Bitcoin and ethereum.
all cryptos are good for long and short term investing but based on my on analysis , bitcoin is more suitable for short term because its value can fluctuate too much while etherium on the other hand is verry stable and only increases for a certain period of time .
Etherium imo , is also suitable for currency purpose as it is more cheaper and faster in terms of procesesing time . so overall you should alocate more percent on bitcoin because bitcoin is the one that can give you a huge profits .
