Hi what filters do you use in dexscreener to find potential rugpulls or detect coins that are not a good option to scalp?
The only significant things I've seen pro shitcoin traders look out for is locked liquidity and if there are holders with a large percentage of the total supply. If there is, then it's a no no. Also, if liquidity isn't locked too.
And what is the minimum amount to start trading these solana meme coins?
I haven't tried it yet but you can do with as low as $2. I have tried personally. I haven't tried $1 or less. Another important think to note is that you can only use such amount on solana. On Ethereum Mainnet, it won't work because gas fee is usually above $1.
I know that in exchanges like mexc, bitget and I know I can start trading with less than 1dollar...but
Depends on the exchange. No two exchanges are the same. You have to check their FAQ and terms of service too. On binance, your trade needs to be a minimum of $10 on either side (buyer or seller) if I remember correctly.
Can I also start trading these altcoins that you find in dexscreener for less than 1 dollar?
On Solana, looks possible to me. Like I already said, I have only tried a trade with $2 and above. The one time the amount traded was $2 was because the price of the memecoin had dropped over 98% and the $2 was the only piece I could salvage.
And is it possible to short these solana meme coins?
Only if an exchange lists them on perpetual futures. MeXC and Bybit are some of the exchanges that lists memecoins on futures from time to time.
