in the world of crypto currencies, none of the prices is impossible. many coins have a high price and arrive at a fall, then lose value. and coins with very bad value suddenly pump and make it have a high price. XLM is no exception. it is very possible. it's just that, pumping and surviving at $100 in this time is very difficult. because most of the crypto market is in bearish mode.
True. Its one thing for a coin to pump to such a high price and its another thing to have enough liquidity or support for the price. However, I don't see xlm getting to that In the next 1 or 2 year because of a simple FA. Keybase in agreement with the Stellar Development Foundation to airdrop 100million xlm for the next 20 months. So you see why I say so
I am also afraid that such huge amounts given away by airdrop may harm the price of Stellar in the near future. However, I think that in the long run it will help to popularize the coin and will have a positive effect on the price.
