Bitcoin is not the only cryptocurrency you can invest in. I have made some recent research and i have come to the conclusion of some project i have been buying into recently
1. Cardano
2. Stellar
3. Oikos
The first two coins do have very good future potential, although the Cardano development team looks very ordinary nowadays. I haven't heard about the third coin (Oikos) and therefore I am not going to comment on it. ADA and XLM are good options, if you want to invest in coins outside the top-10. Both of them went up sharply during the 2017 boom, and then went down even more sharply during the 2018 bust.
from those altcoin i will pick ADA as my main protofolio, this coin will be great in future . ADA team continuesly developt their project for new blockchain technology that acceptable in market.
I've been reading through this forums for the past few weeks and all I see is "this coin is dead" or "everything is a shit coin". Is there any alt coin with potential to invest in or is it only bitcoin?
There are many altcoins available for buy without bitcoin. Due to most of altcoins is already trun into scam or still becoming so. this is why Top altcoins are suggested. If you buy altcoins from top, then no need to analysis deeply because top altcoins can minimize risk and can ensure you, a good return. Do analysis deeply if you can. It is best time to buy altcoins cause market are quite good
its the simplest way to invest in crypto market, top 10 cmc will give profit probability bigger than anther coins.
